Vintage framed drawing / watercolor on paper of 3 football players in action

Varsity vintage vibes—such a cool folk art drawing / painting of 3 football players in action!!! Great for a kids’ or game room! It looks like a black ink drawing filled in with watercolor or gouache. The artist even used a metallic gold paint to highlight the jersey details. Wish I knew the era and team! Framed size is approximately 14 1/2” L x 11 3/8“ H. Image size is about 9 1/2” L x 6 1/8” H. Black metal frame (scuffed) and taupe matboard with gold decorative edge line. I bought this at an antique fair in New England about 15 years ago (probably around 2011, since there is a date notation on the back). The vendor didn’t have any additional info. There is an antique print dealer’s contact name and address on the back. This is being sold AS IS. Please review the photos for condition. I left it in the original frame, which is a bit scraped up, but I thought the patina suited the artwork. Also, there is an old water stain on the artwork, above the middle player. It was there before I purchased it and has not changed visibly while I’ve had it. I never have taken the artwork out of the frame to look at the condition. The paper has an aged color to it.
