Don't know about the one you show but mine was museum authenticated and appraised. Plenty and you show one other? I got mine for my enjoyment, could care less what other ones are out there.

Cardboard Setup... Full Disclosure this was NOT done by me... I found it so funny the first time around I saved it and showed it to a few of my co-workers...
