Jeff, I put paper between each posters when they are stored in the drawers. I snapped those sideways pics with my phone, but I thought I had corrected them before posting them. Guess I didn't. Re: who did the art on the French Invisible Man Returns, I don't know as there is alas no signature.
lecrimesaffiche, the bulk of my collection is made up of US posters, but I do have quite a few French posters as well. I like in particular any horror/sci-fi posters made by the classic French illustrators such as Guy Gerard Noel, Boris Grinsson, Roger Soubie, Jean Mascii, etc... Here are 2 nice sci-fi titles made by Soubie, the first one for Forbidden Planet (1953), and the second one for Time Machine (1960). Both are 47X63, only the first one is linen backed.
