10 printed plans (85cm x 116cm) by the Town Planning Division of London County Council's Architect's Department. The plans were published as part of the Administrative County of London Development Plan ( 1951) and comprise the Programme Map showing London in 8 sheets at 6" to 1 mile scale. The sheets are coloured and have a complex legend which enables representation of residential density, land-use, location of facilities and designated open spaces. Development phases are also shown. There are duplicates of sheets 2 and 4 with some hand additions.
