The 1975 Topps set consists of 660 standard size cards. The design was radically different in appearance from sets of the preceding years. The most prominent change was the use of a two-color frame surrounding the picture area rather than a single, subdued color. A facsimile autograph appears on the picture, and the backs are printed in red and green on gray. Cards were released in ten-card wax packs, 18-card cello packs with a 25 cent SRP and were packaged 24 to a box and 15 boxes to a case, as well as in 42-card rack packs which cost 49 cents upon release. The cello packs were issued 24 to a box. Cards 189-212 depict the MVP's of both leagues from 1951 through 1974. The first seven cards (1-7) feature players (listed in alphabetical order) breaking records or achieving milestones during the previous season. Cards 306-313 picture league leaders in various statistical categories. Cards 459-466 depict the results of post-season action. Team cards feature a checklist back for players on that team and show a small inset photo of the manager on the front. The following players' regular issue cards are explicitly denoted as All-Stars, 1, 50, 80, 140, 170, 180, 260, 320, 350, 390, 400, 420, 440, 470, 530, 570, and 600. This set is quite popular with collectors, at least in part due to the fact that the Rookie Cards of George Brett, Gary Carter, Keith Hernandez, Fred Lynn, Jim Rice and Robin Yount are all in the set.
