We come across lots of similar covers but these two from Gold Medal Books are truly twins. The first, for Walt Grove’s The Man Who Said No, is uncredited, but the second, for Mike Heller’s So I’m a Heel, was painted by Barye Phillips. These could actually both be Phillips, looking at them. He sometimes didn’t sign his work. But absent confirmation, we’ll just say both are great. 1950 and 1957.
