Groucho glasses, also known as nose glasses, the beaglepuss, or the GM 20/20s, are a humorous novelty disguise which function as a caricature of the stage makeup used by the comedian Groucho Marx in his movies and vaudeville performances. They typically consist of black frames (either round or horn-rimmed) with attached features including bushy eyebrows, a large plastic nose, bushy moustache, and sometimes a plastic cigar. Considered one of the most iconic and widely used of all novelty items in the world, Groucho glasses were marketed as early as the 1940s[1] and are instantly recognizable to people throughout the world.[2] The glasses are often used as a shorthand for slapstick[3] and are depicted in the Disguised Face (🥸) emoji.[4][5]
