The 1989 Topps Big Baseball card set consists of 330 cards measuring 2-1/2” by 3-3/4” with dual images of the player on each card front. A headshot of the player is superimposed atop an image of the player in-action with his name printed in blocks at the bottom, surrounded by a colored border and a white perimeter. The Topps Company logo appears at the lower right corner of these horizontally printed cards. Each back shows the player’s name, personal information, card number and Topps logo across the top border, a cartoon depicting a highlight from the player’s pervious season and his year and career statistics block at the bottom. Keys to this set include: Barry Bonds (#5), Mark McGwire (#34), Roger Clemens (#42), George Brett (#46), Don Mattingly (#50), Gary Sheffield (#55), Tony Gwynn (#58), Ozzie Smith (#110), Kirby Puckett (#167), Cal Ripken, Jr. (#286) and Randy Johnson (#287).
