Mr. Jack Mr. Jack was an American comic strip by Jimmy Swinnerton which ran in William Randolph Hearst newspapers from about 1903 until 1935. He may be the first developed "funny animal" character, a type that has since become a staple in the comics medium. The series may also be one of the earliest spin-offs of another comic strip. The character of Mr. Jack, a philandering playboy tiger, emerged around 1898 in Swinnerton's earlier Hearst feature, The Little Tigers, which started in 1896.
