One has to wonder how someone so obviously gullible (naive, vain, dumb?!?) could accumulate (and keep) that size of an estate. I'd be willing to bet if anyone had seen that collection (while delivering pizza, for example) and told the owner it was all fraudulent garbage - he'd have had you arrested.
I don't blame the estate company so much as it's their mission is to maximize the bottom line (and their commission). But by charging prices shown in the photos without obviously checking for authenticity, they'd might want to double check their liability as someone is going to be pissed.
