Did you try amazon.com or e-bay? Try those if you really are desperate. If your not then don't bother with those sites. Write a letter to midway saying that you won't only take some merchandise they don't want off their hands for them, but you'll PAY for it. They'll probably piss their pants in exitement.

This is not a poster exactly,it's a Midway ad from MK2 on the original release of the game,check it:

I love that picture and i would give a left nut for something like that to be hanging on my wall. Thanks for the help

If you really like it and your kida crafty just enlarge it a bit and do a multi-print. You could probably get something 2' X 1' that wont look too bad.
