1950-51 Toleteros In Action #18 of American Negro League stars Bob Thurman and George Scales. Graded a 1 by PSA. The image depicts Thurman being congratulated by 3rd base coach Scales after hitting a home run. Scales has a legitimate case for being inducted into the Hall of Fame. 

Issued alongside the standard 1950-51 set, this In Action companion release contains 178 numbered cards featuring full-color in-game action photography from the Puerto Rican Winter League. The cards measure about 1¾" x 2½", and have blank backs, and are considered among the rarest and most visually impressive Caribbean baseball issues of the era.
