An auctioneer friend is planning to sell a hundred or so limited edition prints, forty of them framed and the rest in sleeves, from artists such as Doolittle, Lyman, Terpning, Isaacs, etc.. He's already called the publishers, who suggested he contact their local dealer, which he hesitated to do, so he called me wanting to know how to value them. All I knew was to tell him about the Art Expediter, which we used at the place I worked at 17 years ago and which carried such prints. I told him it would only show one part of the secondary market, not places like eBay, but that it might be helpful. Any other good ideas, or is that still something to use?
