Probably a pretty good price, given the scarcity and daft prices of fine copies. I'd have bought it.
The copy arrived today. Other than the sunned spine on the dustjacket, and some minor wrinkling to the top 1mm of the dustjacket, it is in fine condition. It was in doubled brodart sleeves with lots of wrinkles, with non-archival tape holding it all together, but with those removed and thrown away the jacket itself was pretty well protected and in good shape other than the above. The book looks unread.
