Those crazy people at Abe Books are always looking to get more money. They sent me an email all about their wide variety of unusual book covers. Quite pricey, but quite amazing. They have everything from pigskin to snakeskin. On the left, The Complete Tales & Poems of Edgar Allan Poe in 22-karat gold, and on the right, Fetish: Masterpieces of Erotic Fantasy by Tony Mitchell, in Rubber. Go here to see their most unusual bindings.
