A very contemporary design for the cover of the c. 1970 street plan for the London Borough of Hackney – then a relatively ‘new’ local authority formed as part of the 1965 reorganisation of London’s local governance. The rings represent the 32 boroughs with the solid disc being Hackney and it is also helps to denote the location within the north east of the capital.
The font in use is ITC Souvenir Bold, which was among the first batch of typefaces to be released by ITC on its launch in 1970.
