In 1968 Paolozzi was appointed to the ceramics department at the Royal College of Art, London. Shortly afterwards he was invited to make a set of plates by the firm of Wedgwood. The prototypes were made with the assistance of David Queensberry, Professor of Ceramics at the College. Paolozzi?s geometric designs were made in the lithographic studios at the College and transferred onto the plates at the Wedgwood factory. There were six different plates, each a variant on the same geometric theme, issued as a boxed set.
