1990 Topps Traded Baseball marks the first time the set was available both as a box set and through wax packs. However, its lackluster checklist prevents the set from standing out in almost every conceivable way.
Keeping the same colorful design from 1990 Topps Baseball, the late-season update has 132-cards. They are noted with a 'T' suffix on the numbering. Variation collectors can chase after two different versions of every card. Those inserted in the factory set use white card stock, leaving backs bright. Cards from wax packs have a grey card stock on the back. Neither version carries a premium.
Key rookies in 1990 Topps Traded Baseball include John Olerud, David Justice, Carlos Baerga and Travis Fryman. Dave Winfield and Gary Carter are among the veterans to appear with new teams.
