This study examines caricatures as they appeared within popular Parisian magazines in mid-nineteenth century France at the time of the 1867 World’s Fair. Chapters compare the comic mockery of several of the most important satirists of this time, including Amedee de Noe, or “Cham” (1818-1879) as he was more popularly known, and Honoré Daumier (1808-1879). A major theme within the analysis is how these caricaturists secretly used argot (street slang), as documented in two slang dictionaries by Parisian litterateur, Alfred Delvau (1825-1867), within their comic images to carry hidden encrypted messages in order to evade the censorship of the day.
