Schultz Athletic Goods was out of New York. Whitey Whitehead was a utility infielder for the NY Giants in the 1930's. That may explain how he came to endorse a Glove for that manufacturer. Your glove has similarities to the Ken-Wel Brand, also out of New York. Ken-Wel may have made the glove for Schultz Athletic Goods. Your glove is from an obscure manufacturer featuring an obscure player. There is a market for that especially among collectors who want every player from a particular favorite team. The glove is high quality which really helps, with the only down side being the worn off cloth patch. Someone may give you $100 if they really needed Whitey to complete a team collection and the Ken-Wel link was interesting to them. Check out
