Happy Hooligan — St. Louis Republic, May 10, 1903

This front page of the St. Louis Republic (Sunday, May 10, 1903) is dominated not by a comic strip but by news of the 1904 World's Fair—103,337 admissions to Dedication Day, France's planned Grand Trianon reproduction, a policeman shot—alongside the paper's promotional awards contest. The Sunday comic supplement it heralded, featuring Frederick Burr Opper's Happy Hooligan, rode inside. Opper's tin-can-hatted tramp, launched in 1900 for Hearst, was among the first recurring newspaper comic characters to use consistent sequential panels and expressive visual shorthand. These Hearst and Pulitzer Sunday pages—and their daily strip siblings—supplied the reproducible page formats, recurring casts, and panel grammar that publishers would physically repackage into the first comic books by the early 1930s.
