Exceedingly scarce pin from the 1896-97 Whitehead & Hoag set, commonly known as "Cameo Pepsin" due to the advertisement sometimes present on the reverse of the pins (though the pins are often found with or without Cameo Pepsin advertising). The first large set of pins to feature baseball players, more than 140 subjects are known and more are added to the checklist as they are discovered. Typically subject to image fading and other condition flaws due to age, the pins are quite condition sensitive today. 

The only example graded by PSA, this example of Edwin Hutchinson's Cameo Pepsin pinback has earned a relatively high grade from PSA despite significant fading to the image, as well as what appears to be mild surface wear.  The advertising information on the backing paper remains clean and intact.  A scarce example from a very desirable 19th Century issue.
