"John Petts (1914-1991) is one of the outstanding wood-engravers of the twentieth century. His prints featuring Welsh mountains and the people who live amongst them reflect his deep concern for the history of the land and are distinguished by his profound understanding of the physical and psychological properties of light. Extensively illustrated, John Petts and the Caseg Press spans the entire career of this reclusive artist and offers the first account of the private press he founded in Snowdonia in 1937."--BOOK JACKET.
