The blue water commands the page. On the 1977 A-O-A sheet it forms a broad crosswise pause between Kowloon and Hong Kong Island, wide enough to hold ferry lines, tunnel approaches, piers and a compass rose. A visitor beginning with that expanse would not first encounter a tidy street grid. They would encounter separation—and the many systems devised to cross it.
I had expected these three folding maps to be straightforward guides. Their dates are close enough to suggest repetition: December 1975–January 1976, November–December 1977 and March–April 1988. Open them together, however, and each describes a different arrangement between geography, travel and commerce. The earlier sheets offer a set of orientation mini-maps at several scales. The later one enlarges the street map and places its airport purpose in the heading. Throughout, advertisements occupy the border and sometimes enter the cartography itself.
The group rewards comparison because the basic vocabulary remains stable. Tsim Sha Tsui faces Central across Victoria Harbour; Kowloon stretches northwards; Wan Chai and Causeway Bay continue east along the island. Against that fixed geography, smaller evidence begins to register: an exchange rate, a revised business directory, a changed hotel name, a bus note, a different treatment of Kai Tak. These are not decorative variations. They are the means by which a near-duplicate map can be placed in its own moment.
The blue interval
A-O-A did not reduce Hong Kong to a single continuous plan. The orientation sheets shift scale repeatedly. One panel gives a broad view of the New Territories and Hong Kong Island; others enlarge Tsim Sha Tsui, Central, Wan Chai and Causeway Bay until individual buildings and businesses can be located. The visitor moves between these frames rather than following one unbroken map.
Victoria Harbour makes the change of scale intelligible. On the broader view it is the water dividing Kowloon from the island. On the district plans it becomes a working space: Star Ferry routes, piers, anchorages, approaches to the Cross-Harbour Tunnel and the edges of reclaimed land. The blank-looking blue is crowded with movement. It is both the obstacle and the organising device.
This arrangement also corrects the instinct to read a city map only through roads. Ferries matter here because the paper is written for somebody deciding how to cross, not simply how to walk. The ferry routes and tunnel approaches show that crossing the harbour mattered as much to the visitor as following the street grid.
December 1975, folded into January
The earliest sheet dates itself unusually well. Its title block reads “December-75/January-76” and names Walter K. Hoffman, A-O-A Ltd. and A-O-A Offset Press Ltd. The same block explains that a larger map pack could be bought for HK$3, listing separate maps of the whole colony, the urban area, Tsim Sha Tsui, Central, Wan Chai, Causeway Bay and Macau. The free sheet is therefore both guide and sample: useful on its own, but also an advertisement for a more extensive cartographic set.
Beside the title sits a dense conversion table headed by a rate of US$1 to HK$5.00. It should not be detached from the issue and used as a general history of exchange rates; the sheet itself warns that the open-market money-changer rate fluctuates from day to day. As dating evidence, though, the table is excellent. It belongs to this printing and shows the sort of immediate calculation A-O-A expected a visitor to make.
The orientation copy addresses readers in English and Japanese, while names and labels across the maps also appear in Chinese. These languages are not ornamental flourishes. They describe the imagined users of the guide and the work the paper was meant to perform: bringing different visitors from arrival point to hotel, shop, restaurant, ferry or district.
A familiar room, rearranged
Two years later, the layout behaves almost like a familiar room whose furniture has been moved. The 1977 sheet keeps the harbour, the district maps and the exchange table, yet the title is now flanked by the words “Official Map” and the marks of the Hong Kong Tourist Association and the hotel association. The printed conversion rate is US$1 to HK$4.70. Shops and hotels have shifted position in the directories; new advertisements compete for the same limited border.
One face of the sheet is especially candid about the commercial company kept by a tourist map. An A-O-A Macau Gambling Handbook occupies the upper-left corner; restaurant, antiques, watch, airline and massage advertisements surround plans of Tsim Sha Tsui and Central. Their presence does not turn the geography into fiction. It reveals the economic setting in which the guide was made and given away.
The arrangement demands a careful distinction. Period advertising can establish names, addresses, products offered and the claims businesses made about themselves. It offers no proof of a shop’s quality, of any visitor’s presence or of the length of a firm’s trading life. The safest reading keeps the claim attached to the printed panel. That restraint leaves plenty to examine: the prominence of duty-free goods, jewellery, watches, tailoring, hotels, restaurants and organised excursions; the way shopping addresses double as map coordinates; the assumption that finding a city and buying within it might be parts of the same activity.
When the airport enters the title
By March–April 1988, Kai Tak is no longer only represented on the map. The heading declares that the street sheet was “for distribution at Kai Tak Airport”. That line changes the status of the object. It is not merely suitable for a visitor who happens to have flown in; arrival by air is built into the issue’s stated purpose.
The Kowloon side makes the transition from aircraft to city practical. An Airport Airbus panel lists routes from Tsim Sha Tsui, Hong Kong Island and the Causeway Bay–airport service, with fares and approximate frequencies. A separate note gives taxi information. Around them are furriers, pearl dealers, craft shops, furniture makers and other businesses trying to secure attention at the beginning of a stay.
The paper now occupies a sharply defined historical interval. Ten years after this issue, Kai Tak closed and the new airport at Chek Lap Kok began commercial operations. The Civil Aviation Department records the old airport’s official closure at 1.20 a.m. on 6 July 1998. Nothing on the 1988 sheet anticipates that ending; its airport is entirely present tense, a working gateway joined to hotels and shopping streets by bus route, taxi fare and printed line.
The reverse carries Hong Kong Island from Central through Wan Chai to Causeway Bay, while a small territory map restores the wider setting. Here too the sheet alternates between breadth and detail. It lets a reader see the island as part of the harbour geography, then drops them among individual roads, hotels, ferry piers and commercial addresses.
Addresses around the edge
An advertisement on these sheets is also an address. Many panels supply a shop number, hotel arcade, floor, telephone number and map reference. The border therefore sends lines back into the plan. A pearl dealer at one edge points towards Tsim Sha Tsui; a furrier or craft shop occupies a labelled block; a restaurant listing turns a street coordinate into an invitation.
That relationship is easy to miss if the advertisements are cropped away as untidy framing. Kept intact, they show how the guide financed or justified its circulation and what kinds of expenditure were imagined for the visitor. They also assist comparison. A business that appears in 1977 but not in 1988 is a clue to a changed edition, although absence alone cannot establish when the firm opened or closed. The map dates the advertisement; the advertisement does not automatically date the business.
Lay the sheets beside one another and begin at six points: the issue line; the named compiler and printer; the exchange table; the Tourist Association wording; the treatment of Kai Tak and surface transport; and the businesses tied to map references. Only then compare the street coverage. The broad geography may look reassuringly familiar while the useful differences wait in small type.
A city reduced without becoming small
The achievement of these maps lies in compression. Each sheet fits a territory view, several districts, transport advice, commercial directories and a persuasive border into paper small enough to fold into a pocket. Yet Hong Kong does not feel diminished. The repeated shift between territory, harbour and street produces the opposite effect: a city whose scale changes according to the decision in front of the reader.
Across thirteen years, the harbour remains the hinge. Shops change, exchange figures change, the airport acquires new prominence and the layout grows denser, but the blue interval continues to explain the relationship between Kowloon and the island. Folded, each map is a compact visitor’s aid. Opened together, the three sheets preserve different versions of arrival.
Bibliographical note
This editorial examines three original A-O-A sheets compiled by Walter K. Hoffman: a December 1975–January 1976 orientation mini-map, a November–December 1977 orientation mini-map and a March–April 1988 street map issued for distribution at Kai Tak Airport. Dates, exchange tables, map titles, transport notes, business names and advertising claims above are taken from the photographed copies. Commercial claims are treated as period copy rather than independently verified endorsements.
For wider context, the Hong Kong Government Records Service catalogues an A-O-A orientation mini-map dated February–March 1977 within its guidebooks and promotional materials. The Lands Department makes historical maps, old survey sheets and old urban maps available for comparison, while the current e-HongKongGuide continues the official street-map and gazetteer function in digital form. The date of Kai Tak’s closure is drawn from the Civil Aviation Department’s 1998–99 review. Their role here is contextual: none is evidence for the accuracy or complete distribution history of every A-O-A edition.
