This is one of a number of colour lithographs bearing the series title 'Opus' in which Gabo explored fluid sculptural forms using a two-dimensional format. He first began printmaking in 1950 after meeting with William Ivins (formerly curator of prints at the Metropolitan Museum), who visited his studio with a printmaker's kit - comprising a wood block, cutting tools, paper, and inks - and also offered practical advice. Gabo became absorbed by the possibilities of printmaking, experimenting with colour, tone, paper (he preferred Japanese), the orientation of the image, and with the type of wood used for the blocks including boxwood, pearwood, cherrywood, and even a piece of mahogany sawed off from a piece of furniture. He continued to make prints for the next quarter of a century.
