This is a laughable as it gets.

Check out the "Marie River (Mariano Rivera)."

This is as laughable as it gets.

And what is this suppose to be!!!

Worthless COA from "The Nascar Autograph Depot."

What a joke this is!!!!

Here is a typical mass-produced set of Mantle/Williams forgeries with a worthless COA from Stephen Rocchi and his Guaranteed Forensic Authenticators (GFA).

Produced on inkjet paper.  Basically, it's a copy of a set of forgeries.
