The 1975 baseball card issues were marked by an extraordinary number of key rookie cards, from players who would move on to be huge stars.  Hall of Famers Jim Rice and Gary Carter, superstars Fred Lynn and Keith Hernandez, and of course, the year's keys, of eventual Hall of Famers George Brett and Robin Yount are among the key cards in both the Topps issues and also many of the regional and food issues of the season.  Presented here is a grouping of three cards, each featuring Brett or Yount, each graded by PSA.  The collection includes the following:  1) 1975 Topps #223 Robin Yount (HOF RC): Graded VG-EX 4 by PSA, a strong and sharp example with a L-R centering issue, along with some areas of light surface discoloration.  2) 1975 Topps #228 George Brett (HOF RC): Graded EX-MT 6 by PSA, sharp and clean with some light corner touches and a L-R centering issue.  3) 1975 SSPC #167 George Brett (HOF RC): Near-perfect centering, sharp and crisp with bright, white borders.  Three cards total.
