Brenton is the inventor of the "writing on the back" version. This is NOT on the original prop and any prop with this detail is simply copying Brenton's version. And yes, Mezco Toys recast my version of the Copper Bones to make their "Official" version. This version is even on display in the Pirate Museum in St. Augustine, FL. Brenton and my replicas have also been used in other official licensing such as the 25th anniversary calendar and Bluray box art.
