Here is a video (please excuse the quality) of the rarely seen precredit sequence for LO MANO DE UN HOMBRE MUERTO (1962), the Spanish language version of THE SADISTIC BARON VON KLAUS. A 2.35:1 scope film, the French version had been released on Blu-ray. Unfortunately, this Spanish version has not had a HD release. Also, the later sequence, featuring Hugo Blanco torturing and murdering Gogo Rojo, was censored in this version.
This sequence features a white masked killer in black, anticipating the sadistic "shape" in Mario Bava's Giallo foundation stone, BLOOD AND BLACK LACE (1964).
