Remarkable 1906 folding postcard depicting a crowd of spectators milling about on the field at the Polo Grounds. An apparent size of 5 1/4" x 3 1/2" the card opens to reveal a full 1906 schedule and scorecard along with a folded-out paper strip of individual player photos. The photos which are extremely delicate are all intact but many are separating at their seams. Players pictured include Hall of Famers John McGraw Christy Mathewson Joe McGinnity along with favorites Bill Dahlen Mike Donlin Dummy Taylor and more. Though the scorecard inside is unmarked the reverse of the postcard does contain some minor pencil markings; aside from that the card does exhibit some age-related toning and wear to the corners edges and folds. A seldom-seen postcard with exceptional significance.
