EDIT: Found it. The pic is in SWFreak's Flickr photostream from this year's D*C.
Lamas was born Fernando Álvaro Lamas y de Santos[1] in Buenos Aires, Argentina. By 1942, he was an established movie star in Argentina. In 1951, he signed a contract with Metro-Goldwyn-Mayer and went to the United States to play "Latin Lover" roles.
