I got the stills as said earlier from a guy who worked at a cinema from the mid 30's through to the 50's. He was retired when I met him, I had gone to buy some 8mm films from him. When we were talking I was telling him Horror films were my main collecting area, he said there was some Famous Monsters of Filmland mags he had in a box. At the time I was 5 missing from a full set so Said I would take a look. Lo and behold, there was about 14/15 of them, and 4 I didn't have. Wow I thought 4 missing numbers in one go. Now at this point he was lifting them out of this box and handing them to me, he says do you collect F.O.H. stills, to which I replied "yes of course", and he lifts out about 200+ F.O.H. stills. The first few were old not very interesting films, and only two of one title, four of another, Halfway down I come across The Maltese Falcon, Oh hell I thought, and started counting.....There was eight, total disbelief, and as I picked up that last still, it unveiled the Casablanca one, I started counting them again, and eight of them!!! what are the chance's. So I bought everything he had.
The Sensitised paper thing is it's not Photographic paper, my Guess was, as this was during WW2 with all the rationing, the stills were put straight on to poster paper, as they are very thin. I maybe wrong it's only my guess, maybe Bruce has some knowledge of this, or if anyone in the U.K. who was around at the time.
Weather any turn up Juli, I did see a set which was a surprise to me as I thought mine maybe the only one's to survive. It was a few years ago in a local, and I must say poorly advertised Auction. I thought I may steal these, being a general Auction but they went over £2000, so a bit rich for me. That's the thing I love about collecting, you just never know what's around the corner.
