From the 1947RR pressbook, these Frankenstein/Dracula combo posters... the US OS and the 3sh. Spectacular, imo!!
Do copies of either of these exist?
Unfortunately, just like the half sheet and insert for the single films, that combo one-sheet is also duo-tone.
And while some people may say the duo-tone pieces are nice, the demand for them is very low; I had a nice unrestored half sheet for Dracula listed on my old site at $2500 for the longest time (and around the time I had sold two copies of the one-sheet at $42,000 and $47,000 each).
It was quite baffling
