Jan Le Witt

Jan Le Witt (1907–1991) was a Polish-born British abstract artist, graphic designer and illustrator. He had a long professional partnership with George Him. As a design company, Lewitt-Him brought an innovative use of colour, abstraction and symbolism to commercial design. They established a reputation for fine poster work during World War Two and for exhibition displays, most notably with the Guinness clock for the Festival of Britain. The partnership dissolved in 1955 when Le Witt decided to concentrate upon his own, often abstract, art. Provided by Wikipedia
