The problem with all the posters is their stupid non-standard size. The arcade posters are all Japanese B1 size (72.8 x 103 cm), which is like an inch and a half too long for standard American frames, which means if I want to get them framed, they would have to be cutom-framed. When I've asked for quotes on frames that size, the typical answer is around $150 apiece. So, I've just laminated them at Kinko's for around $20 apiece and used those 3M wall hanging tabs to stick 'em up on the wall. I still have to get a few of them done, though.
I'll see if I can dig up my pictures of my walls and post a link.
