Exactly the same thing I thought when I first saw it... I wondered where it was from and no one could tell me!!!
I found these images a some time back when doing a search on Oddworld. They were on some obscure gaming site called PSG or something like that.
Here are the two that I have
This one is of poorer quality
A while back I picked up the Abe's Oddysee demo from eBay (as in the CD version released for promotional purposes) ... and although you don't play Scrabania in the demo, it does have the exact same picture on the back cover.
I get the feeling that this may have even been in an early movie that the gaming press saw (just like at Gamestock or last year when there was a demo to selected press).
I thought it would make a very unique personal photo as it's not a common image!
