That 1967 Topps Venezuela Mantle find could be huge...
Corndog might have called in the cavalry with that Mantle find. This card is owned by US Congressman Chris Collins of New York. The Congressman should be alerted not only of this card, but this thread and this fraud within the hobby. I don't think these fraudsters want to go down the path of congressional investigations.
