Several members of the 1904 Cincinnati Reds had booster buttons manufactured, and this rare issue from Stenzel's Baseball Exchange is of Peaches O'Neil, who only played eight games that season - his only one in the major leagues. There is a paper insert on the back of the button but the metal retaining ring is missing. The front of the pin is EX+ to EX-MT. Stenzel's was a business located just across the street from the Cincinnati ballpark at the turn of the 20th Century.
