A motif found in the majority of horror movie poster and lobby card artwork for any country: the female victim. The strategic dappling of blood across her ample bosom accentuates the terror of helplessness. I doubt Dungeons of Harrow (1962) brings, as the lobby card states, all the suspense as the major productions of Alfred Hitchcock. I don't think suspense is the key audience attractor here.
