Anthea Alley trained as a painter at St Martins School of Art and the Royal College of Art. She worked in a variety of media but is perhaps best known for her sculpture and reliefs. This is one of a series of sculptures made chiefly from machine stampings. These are the pieces of metal that remain after various standard shapes have been stamped out of the metal by machine. The artist began to work with these left-over pieces of metal in 1962 and used a variety of metals and patterns to obtain effects of transparency and movement in her sculpture. She generally confined herself to one type of stamped out shape for each work. Anthea Alley is represented in a number of public collections.
