The most important baseball card of the 1970s, the rookie card of Hall of Famer George Brett, is certainly the key to the 1975 issue.  While the card is certainly not scarce, the quality control issues with this set make it difficult to find high-grade examples, especially grading above the NM-MT level.

Consigned from an extremely high-grade 1975 Topps collection, this example is nearly perfect. Some extremely minor color loss along the right edge and very faint foxing on the back are the only possible issues keeping this George Brett rookie card from grading even higher than the PSA MINT 9 it has achieved here.
