1952 Topps Master Set Collectors! Take this opportunity to seize the offered 1952 Topps Baseball #307 Frank Campos. Graded 30 Good 2 by SGC, this oddity displays a black star on the reverse in comparison to the much more common two red stars. Despite moderate obverse wear, this seldom encountered keepsake still presents nicely and is an ideal choice for the discriminating oddball collector. One of only seven copies confirmed by the grading service.
