Considered the first comic book with original material ever produced, 1933’s Detective Dan, Secret Operative No. 48 was a landmark. It only lasted one issue before morphing into the Dan Dunn newspaper strip. At first a blatant copy of Chester Gould’s Dick Tracy, Dan Dunn quickly developed into an exciting and compelling series starring a rough and tumble Secret Service agent who exacted violent retribution on any criminal who dared cross his path. This book reprints the entire first year of daily comics.
