Snoopy, the comic-strip character, is a spotted white beagle with a rich fantasy life. The pet dog of the hapless "Peanuts" character Charlie Brown, Snoopy became one of the most iconic and beloved characters in the history of comics.

Lying on the roof of his doghouse, Snoopy spent much of his time daydreaming. In one of his recurring flights of fancy, he was the World War I Flying Ace, who, sporting pilot’s goggles and a flowing red scarf, with his doghouse transformed into a fighter plane, waged fierce aerial battles against his nemesis, the Red Baron. This rivalry was the subject of a pair of popular novelty songs by the American rock group the Royal Guardsmen in the mid-1960s. Snoopy’s other alter egos included the jazz saxophonist Joe Cool, a lawyer and a soldier in the French Foreign Legion.

Snoopy was prominently featured in numerous "Peanuts" animated television specials and movies, including "Snoopy Come Home" (1972), as well as the Broadway musical "You’re a Good Man, Charlie Brown" (1967), and the feature film "The Peanuts Movie" (2015). In the 1960s, Snoopy became a mascot for the National Aeronautics and Space Administration (NASA).
