Glossy 8×10 black and white half-length lobby still portrait from Congo Crossing (1956), boldly signed in blue felt tip ink.  Near very fine condition, with minor border creasing.  The 1950s screen hunk’s  American film career was ultimately scuttled by Universal-International, the studio with which he was under contract, in order to protect the reputation of their more bankable star, Rock Hudson, with whom Nader was (falsely) rumored to be having an affair. He successfully continued his career in Europe until the mid-1970s, when illness forced him to retire from acting.
