Found this article while searching to find out information about Karl Rove's collection. Obviously the author isn't a fan of Mr. Rove on several levels including stamp collecting. However, the remainder and bulk of the piece is an interesting tongue-in-cheek narrative suggesting that FDR was actually polydactyl as noted in a 1947 stamp from Monaco (C16) and not crippled by polio as most people believe. Worst of all FDR isn't using tongs to hold the stamp in his fingers! An amusing piece; just thought I'd share.
