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 as they are discovered. Typically subject to image fading and other condition flaws due to age the pins are quite condition sensitive today. Presented here is an example featuring Cincinnati infielder Charlie Irwin some minor foxing and more pronounced wear evident around the curl. This example appears to have not featured Cameo Pepsin advertising on the reverse much of the Whitehead & Hoag advertising worn away as well. Still an exceptionally rare specimen.
