Some concept art, construction and photos celebrating the 45th Anniversary of the Haunted Mansion. The concept art is by Ken Anderson in 1957, the color art by Sam McKim in 1958. The sign was made during construction of the Mansion based on a comment Walt Disney made upon returning from a London trip that he was seeking out ghosts looking for a new home.
Imagineers Yale Gracey and Bill Justice pose with some of their creations, including a rare shot of Yale Gracey with the Hatbox Ghost.
