Grignon postcards were issued in 1907 to memorialize the Chicago Cubs' dominant season of 1906.  The set featured 16 members of the World Champion Cubs, including four Hall of Famers.  Considered scarce and desirable today, the horizontal cards have a green background and white border, with the central figure not being an actual player but a teddy bear in a baseball pose.  The player image is inset in the upper-right corner, with a line of infield chatter (i.e. "Good eye, good eye") printed in the center. 

This postcard features pitcher Jack Pfiester in the inset, and is postmarked from Chicago in 1907, though the exact date is unclear. However, the writing on the back is dated by the sender to be October 7, 1907 which is just 5 days before the Cubs won their first of back-to-back World Series.

Centering is terrific, and while the corners are rounded, they and the edges are nicer than the grade would indicate. However, some surface abrasions on the front, writing on the reverse, and light staining keep this card from grading higher. Nevertheless, a very unique card, especially given the context of the time during which it was sent.

SGC has only ever graded 11 total examples of this 1907 Grignon postcard, with only ten receiving a higher grade than the Poor 1 offered here of pitcher Jack Pfiester.
