Matt, from Rashomon, found an "old" link on PCL LinkDump with Egyptian Posters, Egyptian Films. It's a very cool gallery of posters, but the are more, much more on the homepage. Vintage and news posters from Poland, Argentina, Spain, Yugoslavia, Czech Republic and Beatles, Disney, Bond, Tarzan, Godzilla and Elvis posters.

And I posted on my new blog this wonderful poster gallery site: affiches de films. It's a French site with French titles of the films. Hundreds of posters, not all with a good scanned quality, but the good thing is the posters of the French films there, a lot of them.
