I forgot I started this thread. I've purchased a few things from this site the last few years since my first post.
They seem to usually send international posters - in my case, they were from Canada complete with Canadian censor stamps. I do not believe they were listed as being international posters, but they were originals. I can't complain though, I was happy with all of my purchases.
I keep my posters in rolls of 30-35. And flattening then is not an issue either. I just roll them the other way around, hold them for 20 seconds or so, and lay them on the floor if I need a picture.
That's an interesting method,
T. I can't believe I haven't thought of that. I always struggled with trying to flatten rolled posters. I'll try that next time!
