Cards as Weapons by Ricky Jay
VALUE? Copies show up a bit creased at around $200 and twice that for fine copies. Signed should show up as Jay is pretty approachable and was often seen at book fairs etc., being a serious book collector. God bless him. Magicians are often pretty serious book collectors - at one time one heard quite a bit about the highly acquisitive David Copperfield and his awesome collection. It is worth noting that there is also a hardback of the book that is much prized and dealers (who are not mad) sometimes ask $1000 or more for it, although a cautious punter could probably pick one up in the $600 to $800 range - in a jacket.
OUTLOOK. Ricky Jay, for some reason, will not allow the book to be reprinted. Only lousy copies drop beneath $100 (there is one on AMZ at present 'good only, with an "S" shaped bend to it' for $95.) Signed copies are becoming difficult -- only one is available right now, and in paperback, at $480 (signed 'The meagre efforts of a callow youth., Ricky Jay'.) The hardback seems to be showing up more and generally copies are coming home to roost a little. Unless someone finds an abandoned pallet full of them it should hold its value but is unlikely to ascend in price.
