It was a post-war Topps common card. The seller, I'll call "Mr. X" claimed to have put invisible ink on the edges of all four sides to see if the buyer, "Mr. Y" would trim it and re-sell it in graded form. As it turns out, the card was graded by a Third Party Grading company and put up for sale by Mr. Y, and Mr. X asked his friend, "Mr. Z" to buy the card from Mr. Y. When the card got back to Mr. X, he "determined" that the card was indeed trimmed since no invisible ink could be detected on the bottom edge. As a result, Mr. X went on a covert smear campaign inferring that Mr Y and the TPG company president needed to go to jail and the TPG needed be put out of business.
