I've only seen the coin door stickers on Ebay from one seller, but despite his "Title" they are NOT coin door stickers for the original TMNT, they're for Turtles in Time (Colors are different, Mikey is straight up orange not yellow).
Best bet, is the file on localarcade and have somewhere like Staples print it out for you. If you can get that file off localarcade, that damn site NEVER works properly.
Marquees on Ebay, a few people on KLOV have them. I wouldn't pay what Mamemarquees is asking for an inkjet, theres plenty of originals around.
