Does this seem legit? Comes with COA from superstar greetings which appears to be a legit autograph dealer in Newyork based on a Google search, also comes with a pic of him signing.
He uses autopens a lot. I've researched Chevy thoroughly but a little out of practice since its been over 5 years since. It doesn't look like one of his autopen examples but id still try to double check that. Otherwise the signature looks like it could be real.
BC is right though, its easy to forge. After all of my research, i still couldn't trust anything on the secondary market so I ended up buying a leaf certified auto card and gave up looking for him on a photo.
