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 Albert Kennedy pinback graded by PSA, the Cedar Rapids examples quite scarce and desirable.  The EX 5 grade assigned by PSA describes the overall condition of the pin but does not appear to address image fading - the reverse is clean and bright, with very little wear around the curl or at the surface.  The image of Kennedy, however, does exhibit some fading, with below average contrast.
