Circle Press was established in 1967 by Ron King in England. If you search the catalog for Ron King, you will find work that he was directly involved with, but Circle Press produced more work than just that of Ron King. Under Circle Press, you will find exhibition catalogs and checklists, etc. as well as work by Roy Fisher, Keith Please, Willow Legg, and other artists.
The books of Circle Press range from traditional fine press books such as the Prologue to the Canterbury Tales to conceptual works like the Mirror Book. Playful pop ups, puppets, multi-color screenprints, embossings, and letterpress are just some of the elements to expect.
