At its peak, the strip, featuring Superman, was in over 300 daily newspapers and 90 Sunday papers, with a readership of over 20 million.

[1] The daily strip was host to many storylines, unique from the regular Superman comic series.

Other stories of note include Superman saving Santa Claus from the Nazis, World War II-era stories of Superman protecting the American home front, and Clark Kent marrying Lois Lane.

The artwork includes runs by famed Superman artists Wayne Boring and Curt Swan.

Due to the publishing lag time, the daily strip team of writer Whitney Ellsworth and artist Wayne Boring saw what had been created for issue #30, and were able to use him first in the daily strip story "The Mischievous Mr. Mxyzptlk" published from February 21 to July 19, 1944.

While published second, Mr. Mxyztplk was first created for Superman issue #30 and first written by Jerry Siegel and drawn and inked by Ira Yarborough.

Paul Cassidy was the first in a line of ghost artists on the strip and took over the inking and detail work in 1939.

Burnley eventually left to work on his own comic book, Starman, but did return to pencil the Superman Sundays in 1943.

[citation needed] McClure Syndicate, concerned and fearing newspapers would cancel the popular Superman strip if it could not appear regularly and on time, appealed to DC to instead create a spin-off strip, Lois Lane, Girl Reporter, for McClure to use as a filler material for newspaper syndication.

As of 2024, no imprint has yet to publish the Superman daily strips from 1949-1959 as no complete set of viable proofs, or private collections, of those years can be found.
