Bill Gold, one of Hollywood's best-known creators of film posters, has died aged 97. The veteran illustrator had a hand in more than 2,000 posters, including those for Casablanca, Dial M for Murder, and Dirty Harry, BBC reported on Monday. Gold began work at the film production company Warner Brothers in the 1940s. His task was to create artwork that didn't give away a film's storyline.

Gold also designed the poster for Alfred Hitchcock's thriller Dial M for Murder. He was a frequent collaborator with Clint Eastwood. He worked with the actor and director on dozens of films.
