8.5x10-3.8" sheet has wonderful art we believe to have been done by Whitney Ellsworth showing boy in knickers running up to news dealer saying "Say Mister! I Want To Buy The Magazine With Superman!" as the news dealer says "Then You Want A Copy Of Action Comics! Superman Appears In Action Comics Each And Every Month!" Lower left has Joe Shuster inspired image of Superman in red costume with no cape and lower right has image of Action Comics logo. Text at top "Superman Is The Leading And Most Popular Comic Strip In The Country. This Feature Appears Each Month In Action Comics". Text at bottom "Superman Sales Demand Front Display For Action Comics". The rack behind the news dealer has various comic books including "All-American" which was first published in April 1939 and ad does not show or mention the first issue of "Superman" which came out in the summer of 1939 leading us to believe that this flier was published in between those dates. Extreme top margin edge has barely noticeable and very faint lt. moisture mark, a few very faint handling creases. Overall Fine. In light of the recent extraordinary sales of Action Comics #1, it is important to note that there are far fewer of this flier known as opposed to existing copies of Action Comics #1. This flier was only sent to a select few newsstand dealers/distributors and is exceedingly rare. Superb design and historical.
