The front of the 1939 four page flyer promoting the Masked Marvel in Keen Detective Comics

Created by Ben Thompson, The Masked Marvel first appeared in Keen Detective Comics #7 on July of 1939. While the comic book is considered scarce, one can only imagine how rare this four page retail flyer really is.

The flyer features a three-page story and an advertisement for Keen Detective Comics #8 the second appearance of The Masked Marvel. The flyer was distributed from retailers to promote the title and offered 1,000 red masks to the readers. Each reader was asked to submit a letter explaining what they liked about The Masked Marvel. The reader also had to include the top half of the August issue of Keen Detective Comics when submitting the letter to receive a mask. We wonder how many copies of the comics were destroyed in the hopes of receiving a promotional red mask.

Do you own an example of the promotional mask offered? If so, let us know.
