Bowman

Topps' prospect brand, revived.

Topps resurrected the Bowman name in 1989 as a prospect-focused set with an oversized card format (thankfully corrected in 1990 to standard dimensions). The 1989 Bowman Ken Griffey Jr. #220 is one of his four major rookies and the least-produced by a wide margin, though the awkward tall-card format hurts its collectibility. Bowman has since become MLB's dedicated prospect brand.
