I was at a gaming show and snagged a copy of Maniac Mansion with the original Commodore 64 poster for $4 (the disk was tested on a machine there and it didn't load but when I got it home it plays fine!)
I also have a boxed copy of the NES game with the poster and I noticed that they are quite different in size The NES copy is two sided and much smaller (the blue one which is laying on top of the brown (c64) one:
I'm not sure if there are any content changes either (I just snapped the pictures quickly).
I was wondering if a high res scan/photo already exists or if I should try to capture some for posterity. Any suggestions on the best way to do so (The C64 version of the poser is HUGE and won't fit on a scanner bed)
