The cards in this 792-card set measure the standard size. Cards were primarily distributed in 15-card wax packs and 54-card rack packs. For the second year in a row, Topps utilized a dual picture on the front of the card. A portrait is shown in a square insert and an action shot is featured in the main photo. Card numbers 1-6 feature 1983 Highlights (HL), cards 131-138 depict League Leaders, card numbers 386-407 feature All-Stars, and card numbers 701-718 feature active Major League career leaders in various statistical categories. Each team leader (TL) card features the team's leading hitter and pitcher pictured on the front with a team checklist back. There are six numerical checklist cards in the set. The player cards feature team logos in the upper right corner of the reverse. The key Rookie Cards in this set are Don Mattingly and Darryl Strawberry. Topps tested a special send-in offer in Michigan and a few other states whereby collectors could obtain direct from Topps ten cards of their choice. Needless to say most people ordered the key (most valuable) players necessitating the printing of a special sheet to keep up with the demand. The special sheet had five cards of Darryl Strawberry, three cards of Don Mattingly, etc. The test was apparently a failure in Topps' eyes as they have never tried it again.
