Most of the lettering on a piece of sheet music for a song from the 1921 George M. Cohan musical comedy entitled “The O’Brien Girl” was hand lettered in a playful, casual Art Nouveau design with rounded ends.

The characters on that page took on a look reminiscent of cartoon or comic strip wording, and the result is a digital typeface named Cartoon Nouveau JNL, which is available in both regular and oblique versions.
