Provenance: ex-collection of Will Barnet; thence by descent to current owner.
By late 1947, Bob Blackburn had acquired his own lithographic press, and a year later, he opened his Printmaking Workshop in Chelsea, printing for artists and encouraging his friends to experiment in lithography. The artist's interest in abstraction was shared by his fellow printmakers, Will Barnet, Ronald Joseph and John Von Wicht.
