Nice Circa 1915 Spalding Jersey. This particular tag was used during this era. Also, the western style back shoulder design was also indicative of this era. You'll also notice the rare and interesting collar design - an ever so tiny cadet collar that is made from rolling over its collar fabric. This style was seen in early MLB photos form this era.
Unknown team and location, but likely "Dover Athletic Club" from Dover Delaware or Ohio or PA or NH or NJ.
Large adult example. Pullover style in fabulous condition. Has slits on short sleeve hems for sleeve extensions (not found with this jersey) for colder weather, and grommet sewn holes underarm for venting. A high quality jersey of it's day.
