Considering Osvaldo Civirani's Il Diavolo a sette facce is starring two great genre actors (George Hilton and Carroll Baker), I had fairly high hopes the first time I watched it. Unfortunately the film is a fairly uninspired effort. The set-pieces are far and few between and you can see the ending coming from miles away. Not a total write-off, but certainly not the lost masterpiece by any means.
The top locandina is a bit unusual, since it's thinner than usual. The first time I saw it, I thought it'd been cropped by the seller, but I've seen it for sale several times since and it's always had the borders cropped. The bottom one is from the films rerelease in 1977. No info on the poster artist.
