English: In the late 1960s, London Transport appointed a collective of designers, artists and architects who designed all aspects of the Victoria Line. The distinctive designs in each platform seat recess on all of its 16 stations provided much needed colour and decoration and gave each stop its own visual identity. The results were a mixture of direct inspiration from the station name and references to historical details of the local area. The design for Seven Sisters is by is by Hans Unger (1915–1975). The name is derived from seven elms which were planted in a circle with an ancient walnut tree at their centre, on an area known as Page Green. The clump was known as the Seven Sisters by 1732.
