Outstanding grouping of the three key cards from the 1948 Bowman issue, the rookie cards of three immensely popular Hall of Famers.  The collection includes the following: 1) #6 Yogi Berra (HOF RC):  Graded PR 1 by PSA, well-worn with heavy creasing, corner wear and light staining along the top edge.  2) #18 Warren Spahn (HOF RC): PSA GOOD 2, extremely strong, well-centered image with light staining in various areas, not at all distracting, the appearance of a VG/EX card.  3) #36 Stan Musial (HOF RC): BVG PR 1, well-worn with staining, creasing, edge and corner wear.  Three collector-grade examples of the key cards in the 1948 Bowman issue.
