"Gramercy Park" originally sold in the 1982 Sotheby's auction, then reappeared in their failed December 2014 auction. It did sell last June via Bonhams as part of a two-story lot along with 1949's "The Green Rock".
Indiana University at Bloomington holds, in Plath mss II, two typescript copies of "Gramercy Park". One of them has, on the back of a cover page, a small reproduction of George Wesley Bellow's 1920 painting Gramercy Park, pictured below.
The copy at auction appears to be the draft Plath edited to reach the final version as the edits are reflected in one of the copies at Lilly. It also features some comments in another hand, likely one of her teachers at the Bradford High School.
My thanks to Jett W. Whitehead of Jett W Whitehead Rare Books, THE specialist in poetry in the rare books and collectibles world, for letting us know about this auction. With a web address of www.poetryjett.com, how could you, as a reader of Sylvia Plath, not like this guy!
