Sunday strip in the context of Daily comic strip

A daily strip is a newspaper comic strip format, appearing on weekdays, Monday through Saturday, as contrasted with a Sunday strip, which typically only appears on Sundays. They typically are smaller, 3–4 grids compared to the full page Sunday strip and are black and white.

Bud Fisher's Mutt and Jeff is commonly regarded as the first daily comic strip, launched November 15, 1907 (under its initial title, A. Mutt) on the sports pages of the San Francisco Chronicle. The featured character had previously appeared in sports cartoons by Fisher but was unnamed. Fisher had approached his editor, John P. Young, about doing a regular strip as early as 1905 but was turned down. According to Fisher, Young told him, "It would take up too much room, and readers are used to reading down the page, and not horizontally." Other cartoonists followed the trend set by Fisher, as noted by comic strip historian R. C. Harvey:

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.

Toppers usually were drawn by the same artist as the larger strip. These strips usually were positioned at the top of the page (hence their name), but they sometimes ran beneath the main strip.

Irving David Breger (April 15, 1908 – January 16, 1970) was an American cartoonist who created the syndicated Mister Breger (1945–1970), a gag panel series and Sunday comic strip known earlier as Private Breger and G.I. Joe. The series led to widespread usage of the term "G.I. Joe" during World War II and later. Dave Breger was his signature and the byline on his books. During World War II, his cartoons were signed Sgt. Dave Breger.
