Help With a Brooks Robinson Painting
 

I recently picked up this cool original painting of Brook Robinson, which I'm guessing dates to the late 1960's/ early 1970's.....The artist is F.G. Hoyt and the only thing I could find on-line were references to him being a "pop artist' back in the 1940's....Just curious if anyone had seen any of his artwork previously?
