These are nice little items, auction guides. Avaliable on ebay if you watch and wait for maybe $10-20 each. I have both already and they are serious eye candy for all the gadgets, props, pictures, posters...etc. These guides (Sotheby's and Christie's) make good coffee table reading; a fan of Damien Hirst? "Beautiful Inside My Mind Forever: 5 books in total, in a hard slipcase box with pull out pages and sticker sheets at the back." A snip at $152 now. Or how about something more louche, "Elvis Presley Memorabilia: presented in association with Bonhams. Softcover, 179 pages plus". A mere $10.
