-The colours behind the figure and the name tag are wrong
-The colour space behind the figure isn't wide enough
-There is a logo missing by the Kenner logo
-There is a word missing in the French age info.
And if that weren't enough, bidding history would suggest someone was shilling the price up to go over $1000. Subsequently, it would appear as though Star Wars collecting watchdogs have been trying to up the value to the point anyone not seeing this warning won't accidentally buy it.
This seller is also offering an incredibly bad custom Blue Snaggletooth figure, so it seems that this auction isn't a misunderstanding, but an actual scam.
Check out the real MOC Yak Face to see the difference, and not the more accurate bid value.
