Prior to this book the company published road maps only as folded sheets. However, the 1950’s and 1960’s saw a significant increase in car ownership and with it the demand for a single publication covering the UK. Map features, and how they are represented, in this 1961 Geographers’ Great Britain and Northern Ireland Road Atlas is quite revealing. For example, the simple depiction of roads (without road casings) meant that they could be quickly scribed and also benefited from a less critical registration when printed. Also, the green roads are not Primary Routes (this classification was not introduced until 1964 as part of the Worboys Report on signage), but are in fact both B class and minor roads. Interestingly, roads are numbered without their designated class letters.
