Fascinating 1955 Topps Baseball #50 Jackie Robinson (Partial Diamond) variation. Graded VG-EX 4 by PSA. This horizontal rendition of beloved "Bum" was first reported in 2018 and is missing the third base portion of the team logo. As multiple examples have since surfaced, a reputable grading service has started grading affected '55 Robinsons with the "partial diamond" notation. If PSA follows suit, this oddity will certainly soar in value!
