Six-inch map of Belfast and Surrounding Districts in 4 sheets, 1939
Although these sheets were formally published and were subject to copyright deposit, they are not widely known. They might be regarded as the last flowering of the coloured Town Maps from the 1920s. This particular set seems to come from OSNI itself, each sheet bearing in its lower margin a list of what seem to be the negative or plate numbers for each of the colours. Just one sheet is included here; the full set is to be deposited at Cambridge.
