Ken Wel was a well known vintage baseball glove manufacturer. They issued a number of attractive glove advertisements, the best known featuring Lou Gehrig. Cardboard reprints of the signs are common on the market, but many are simple to identify. The most common reprints have little metal rimmed eyelets near the top—metal rimmed holes for hanging . The simple to remember equation is: metal eyelet = modern reprint. You can make out the eyelet at the top of the sign here.
