Original Arcanum Productions One Sheet Poster (27×41) for the Arthur John sexploitation comedy, UNHOLY MATRIMONY (1966)—starring Billy Green Bush, Monica Davis, and Alan Dellay. This sleazy, but fun, exposé of wife swapping in the swinging 60s revolves around a reporter (Dellay) who is sent undercover by his editor to expose a blackmail ring preying on wife swappers. There is some female frontal nudity on the poster. This original one sheet poster is folded and in good condition. This poster is one of the scarcer sexploitation posters from the sixties. Needs linen backing.
