Up for sale is a full set of all 4 cards from the 1989 USPS Baseball Legends set. The Postal Service put these cards in its Legends Baseball Scrapbook and Stamp Album. Each card shows the player's commemorative stamp on the front, with career stats on the back.

Cards included:
Babe Ruth (No. 3)
Lou Gehrig (No. 4)
Roberto Clemente (No. 21)
Jackie Robinson (No. 42)

They're ungraded and look NM or better to me. You'll get the exact cards pictured, and I've shown both the fronts and the backs, so please check the photos.

Each card ships in a penny sleeve and a toploader, in a bubble mailer with tracking.

Thanks for looking!
