[timothyd]

How much would you guess a signed book of Leonard Freed Photographs: 1954-1990 (http://www.magnumphotos.com/Archive/C.aspx?VP=Mod_ViewBoxInsertion.ViewBoxInsertion_VP age&R=2K7O3R1DUX51&RP=Mod_ViewBox.ViewBoxThumb_VPage&CT=Album&SP=Album) be worth? Or actually be able to be sold at?

Thanks.
