I love picking up unique cards from the junk wax era. This Griffey is from the 1990 Donruss Learning Series set. This was a 55-card set produced not for retail, but for use in elementary and middle school classrooms to teach kids about colors, numbers, sports, and baseball card collecting basics. Only 319 of these have been graded by PSA across all grades. Great image of “The Kid” and a sneaky scarce card in a voluminous sea of junk wax!
