Berk-Ross was an almost-challenger to Bowman and Topps in 1951 and 1952, done in by a lack of imagination and suspect distribution.  This PSA 7 of Hall-of-Famer Larry Doby is a good representation of the company's efforts, with a bit of off-registration the biggest culprit here. Corners and edges are sharp and the little attachment nubs are prominent.  This card was not handled much at all back in 1952.
