Clifford Ellis, Variations on Six (Blue on Black)

Clifford Ellis was born in Bognor in Sussex and trained at Saint Martin’s School of Art and Regent Street Polytechnic. He was a graphic artist and illustrator who is best known for the posters he produced for London Transport during the 1930s. Ellis generally collaborated on posters with his wife, Rosemary, whom he married in 1931. The General Post Office, Shell and the Empire Marketing Board were also clients for the couple's posters. They signed their posters C&RE, their initials being in alphabetical order, and they are readily recognizable by their ebullient use of color and form. 

Employed during the war as a camoufleur, along with so many other artists, Ellis was also an official war artist, serving with the Grenadier Guards. Rosemary, meanwhile, was an artist for the Recording Britain project. Following the war, they trained art teachers at the Bath Academy of Art. They also designed a series of nearly 100 book jackets for the New Naturalist series, published by Collins between 1945–82, and were always fascinated by animals and natural history.
