The cards in this 33-card set measure 2 1/2" by 3 1/2" and were issued with an accompanying custom box. In 1985, Topps produced this set for Circle K; cards were printed in Ireland. Cards are numbered on the back according to each player's rank on the all-time career Home Run list. The backs are printed in blue and red on white card stock. The card fronts are glossy and each player is named in the lower left corner. Most of the obverses are in color, although the older vintage players are pictured in black and white. Joe DiMaggio was not included in the set; card number 31 does not exist. It was intended to be DiMaggio but he apparently would not consent to be included in the set.
