The new CGC/JSA Signature Authentication slabs are here! I sent off two books that I had signed by the creators personally sent off to CGC to test out the new signature authentication service they are newly offering after their purchase of JSA.

We are going to unbox them and find out if they were authenticated or not, and what grade they were given!

You can find the shirt I'm wearing at this link!
