Italian-born actor (1895–1926) who became the most legendary sex symbol of the silent era. His premature death from a perforated ulcer induced a wave of fan hysteria unmatched until the modern “paparazzi” age, including riots and suicide attempts by grief-stricken fans. Dashing vintage matte-finish 5 x 7 photo, signed and inscribed in green fountain pen “To Louis Mountain, with best wishes, R. Valentino.” In fine condition, with some rippling to lower edge, and inscription and sentiment a shade or two light from irregular ink flow. The signature itself is clear and bold. PSA/DNA Auction LOA and R&R COA.
