LOU DIAMOND PHILLIPS. Semi-glossy 10×8 half-length color portrait as Ritchie Valens, from La Bamba (1987), boldly signed in blue felt tip ink. Mint condition. Following a few bit roles in films and television, Lou Diamond Phillips catapaulted to success with his starring performance in La Bamba. He has worked steadily in films, television and theatre ever since, appearing in such films as Young Guns (1988) and Courage Under Fire (1996), and surprising legions of skeptics by winning a 1996 Tony nomination for his performance as the King of Siam in a much-praised Broadway revival of The King and I.
