I saw this FDC signed by 15 golf champions and I took an interest in it. The price was a little high, but there were some deceased champions on it, so maybe not so horrible. Then I noticed something. The postmark is April 7, 1977. But, one of the signatures is of Vic Ghezzi who died in May of 1976. Is it common for envelopes to be signed before being postmarked? Or, is this just another forgery? PSA has given their approval (for whatever that's worth). I probably won't buy it because of the price, but is it legit?
