A topper in comic strip parlance is a small secondary strip seen along with a larger Sunday strip. In the 1920s and 1930s, leading cartoonists were given full pages in the Sunday comics sections, allowing them to add smaller strips and single-panel cartoons to their page.

The Sunday comics or Sunday strip is the comic strip section carried in most Western newspapers. Compared to weekday comics, Sunday comics tend to be full pages and are in color. Many newspaper readers called this section the Sunday funnies, the funny papers or simply the funnies.
