Sharing parts of its checklist with the E121 and E126 caramel sets, plus the entire checklist of E135, the D350-2 Standard Biscuit set presents a unique challenge to collectors.  With just 40 PSA graded cards across the entire 200 subject set finding even a single example is a challenging task. This PSA 5.5 holdered example of HOF great George Sisler is, quite appropriately, unique in its singularity in their database. In fact, only seven cards in total exceed the PSA grade seen here. Sharp and bright-looking, front and back, this is literally an unimprovable card from the set.
