Bruce Marshall Rare Books (Cheltenham, England) has issued a catalogue entitled A Complete Collection of the Kelmscott Press. The Chaucer is a quarter-linen binding, with no evidence (in the catalogue, at least) of previous owners.
The collection is evidently meant to be sold as a single entity, but there is no price listed in the catalogue. The books are all housed in matching half-vellum boxes, and the collection includes a few ephemera and Burne-Jones drawings and revised proofs.
(Thanks to Mark Samuels Lasner for giving us a copy of the catalogue.)
