Happy Hooligan — St. Louis Republic, May 17, 1903

The Sunday comic page of the *St. Louis Republic* for May 17, 1903 carries what appears to be a multi-panel strip featuring figures in outdoor exercise or drill, reproduced at the small scale typical of broadsheet Sunday pages of the era. By 1903 the Sunday comic supplement was already a decade into shaping sequential art's visual grammar: recurring characters, panel borders as narrative containers, and speech balloons replacing explanatory prose beneath pictures. Frederick Burr Opper's *Happy Hooligan* — launched in Hearst papers in 1900 — was among the strips syndicated widely to competing sheets like the *Republic*, spreading a shared visual vocabulary of slapstick, sequential gags, and the lovable misfit across millions of American households each Sunday, directly prefiguring the comic book format that would consolidate these pages into pamphlet form by the 1930s.
