The small auction house New England Book Auctions in western Massachusetts is offering 20 lots of Nabokoviana at its Sept. 24th auction (sale #419, lots #64 and #118–136). Included are first editions of American books, a Lolita Olympia Press first, and other Lolitas in English and Russian, inscribed and lepidopterized copies, some journals in which VN’s works appeared, a photograph of VN by Philippe Halsman, and other material. The majority, if not all, of the lots appears to have been consigned by the Ledkovsky family, cousins of Nabokov.
The catalog descriptions aren’t very detailed. I plan to drive up to the gallery next week to examine the goods.
