This puzzle was originally given away by KFC to promote the Super Mario Bros Movie.

I'm done some research on this and even Mario collectors don't seem to have seen one of these before, I've been looking out for another one on ebay for over a year and not one has come up for sale in that time so when I say it's rare I actually mean it (not like certain other listings). This may be your only chance to own this item.
I'll be sad to see it go hence the relatively high starting price; I'm not too bothered if it doesn't sell.

It does have a stain on the back and generally isn't in that great condition (ie lots of minor surface scratches).

Just in case it isn't obvious (as the sizes are different) the big picture is the front and the little one is the back.
