With a limited number of respondants, I am not seeing a HUGE number of tainted sets. Thinking about all of the threads regarding bogus cards on the Bay recently, I can recall a few T206 threads, the Goudey Ruth fiasco, a Cracker Jack fake and that's about it. There have been a few on the Post War side but that's about all I can think of for Pre-War.
Pete mentioned E-90's. Does anyone have any insight on that set? Perhaps a scan or a link to a bad one? As I said, it is one of the sets I am thinking about dving into.
