According to the hump artist that sold it, nothing was wrong and the finish was just discolored there. It's funny the excuses and arguments folks who sell forged and fake items make. Some are actually proud of their work, as if it's a one-of-a-kind Mona Lisa. There would be others who "appreciated his talents." These folks or humpers are nothing but lowlifes.
They actually could care less that they are doing their damn level best to rewrite history. Just give me your almighty dollar.
