After active service in the Second World War, the Scottish artist William Gear moved to Paris in 1947. There he came into contact with Constant who invited him to contribute to the 1949 CoBrA exhibition in Amsterdam. Interior is a transitional work from that period. The strong colour and simplified forms recall Gear’s earlier, freely-handled works. At the same time, the exaggerated outlines anticipate his development of a more controlled abstraction.
