Mutt and Jeff was a long-popular American newspaper comic strip created by cartoonist Bud Fisher in 1907 about "two mismatched tinhorns". Historians regard Mutt and Jeff, originally titled A. Mutt, as the first American newspaper cartoon published as a strip of panels, as opposed to a single panel, making it the first "comic strip" to successfully pioneer that since-common format. It remained in syndication until 1983, employing the talents of several cartoonists, chiefly Al Smith who drew the strip for nearly 50 years. The series became a comic book (initially published by All-American Publications and later by DC Comics, Dell Comics and Harvey Comics), as well as cartoons, films, merchandising and reprints.
