A Chaucer in a private collection, St. Louis (Census 2.194), was sold at Christie’s (New York) on 7 December 2012, lot 114, for $52,500.
The copy has a lightly worn quarter-linen binding and a full blue morocco folding case. It contains bookplates of George Clinton Ward and Louise Ward Watkins, and was also owned by Miles Slocum and Julian Edison. It was previously sold by Christie’s (New York) on 20 November 1981, lot 345.
For brief biographies of Ward, Watkins, and Slocum, see Census 2.194.
[Update, 11 June 2013] Sims Reed is now offering the book for £65,000. (Julian Edison, incidentally, was the unidentified private collector listed in our Census.)
