The rock ‘n roll autograph market is littered with fake or dubious signatures. For this investigation, Inside Edition purchased several guitars from a suspicious company called CharityGROW, which supplies charities with what it says are authentic autographed memorabilia for fundraising auctions. One signature in particular really caught our attention: Tammy Wynette’s. Wynette died in 1998, and, as Laura learned from the manufacturer, the guitar wasn’t even made until 2013. Laura also worked to obtain various legal and business documents on CharityGROW and its affiliates.
