Sandra Blow RA (1925-2006) was one of the leading lights of the abstract art movement of the 1950s. Her works are often on a large scale and consist of abstract collages made up from cheap discarded materials such as sawdust, cut-out strips of old canvas, plaster and torn paper. The use of such materials is designed to create an expressive informality and promote a natural, organic feeling. Her works have a tactile as well as visual emphasis on surface, and her use of simple large geometric shapes lends a feeling of expansiveness and dynamism.
