Lady and the Tramp is a 1955 American animated film produced by Walt Disney and released to theaters on June 22, 1955, by Buena Vista Distribution. The fifteenth animated feature in the Disney Animated Features Canon, it was the first animated feature filmed in the CinemaScope Widescreen film process. The story, which was based upon a short story called Happy Dan, The Whistling Dog by Ward Greene, centers on a female American Cocker Spaniel named Lady who lives with a refined, upper middle-class family, and a male stray mutt called the Tramp.
A direct-to-video sequel, Lady and the Tramp II: Scamp’s Adventure, was released in 2001.
“Happy Dan the Whistling Dog” was published in an early 1940s edition of the “Cosmopolitan magazine”. In 1953 Disney published the first edition of “Lady and the Tramp, the story of two dogs” in hardcover, attributing the authorship to Ward Greene. Currently one of these books is on eBay selling for at least $700. A 1953 edition signed by Walt Disney himself, sold at Christies for over $3,000. See links below, if you really want to. If you won the Lotto, I suppose you could buy the book on eBay, if you wanted to.
