The cards in this 787-card set measure 2 1/2" by 3 1/2". The 1972 Topps set contained the most cards ever for a Topps set to that point in time. Features appearing for the first time were 'Boyhood Photos' (341-348, 491-498), Awards and Trophy cards (621-626), 'In Action' (distributed throughout the set), and 'Traded Cards' (751-757). Other subsets included League Leaders (85-96), Playoff cards (221-222), and World Series cards (223-230). The curved lines of the color picture are a departure from the rectangular designs of other years.

The cards in this 660-card set measure 2 1/2" by 3 1/2". The 1973 Topps set marked the last year in which Topps marketed baseball cards in consecutive series. The last series (529-660), is more difficult to obtain. In some parts of the country, however, all five series were distributed together. Beginning in 1974, all Topps cards were printed at the same time, thus eliminating the 'high number' factor. The set features team leader cards with small individual pictures of the coaching staff members and a larger picture of the manager.

The cards in this 44-card set measure 2 1/2" by 3 1/2", and was the very first Topps Traded ('update' or 'extended') set available. The 1974 Topps Traded set contains 43 player cards and one unnumbered checklist card. The fronts have the word 'traded' in block letters and the backs are designed in newspaper style. Card numbers are the same as the regular set except they are followed by a 'T'. No known scarcities exist for this set. The cards were inserted in all packs toward the end of the production run.

The cards in this 660-card set measure 2 1/2" by 3 1/2". This year marked the first time Topps issued all the cards of its baseball set at the same time rather than in series. Among other methods, cards were issued in eight-card dime wax packs and 42-card rack packs. The ten cent packs were issued 36 to a box. For the first time, factory sets were issued through the JC Penny's catalog. Sales were probably disappointing for it would be several years before factory sets were issued again. Some interesting variations were created by the rumored move of the San Diego Padres to Washington.

The cards in this 792-card set measure the standard size. Cards were primarily issued in 15-card wax packs and 51-card rack packs. Each player card front feaures a large action shot with a small cameo portrait at bottom right. There are special series for AL and NL All Stars (386-407), League Leaders (701-708), and Record Breakers (1-6). In addition, there are 34 Super Veteran (SV) cards and six numbered checklist cards. The Super Veteran cards are oriented horizontally and show two pictures of the featured player, a recent picture and a picture showing the player as a rookie.
