From the FBI Press Release:
The Code of Conduct also provided certain assurances that Mastro Auctions would disclose information about auction items that were altered or restored. After the code was published, Mastro and Allen allegedly failed to disclose alterations and caused restoration work to be done on baseball trading cards, despite assurances that no such work would be performed.
If it was admitted that the Wagner was trimmed, it appears other cards were doctored also, since there are allegations of "restoration work".
The next set of questions that beg to be asked, "Which cards?" "Were they graded by a TPG company?" "Which company" "Who restored them?"

As for my take of Third Party Grading, it was good initially in screening out a lot of amateur doctoring, but has failed miserably in detecting the many of the advanced alterations that are rampant in the industry today.
