Marco Polo

Few characters can claim a debut as historic as Marco Polo's — stepping onto the page in Action Comics #1 (1938), the single most celebrated comic book ever printed, created by the legendary Jerry Siegel and Joe Shuster. That Platinum Age landmark is the ground floor of the entire superhero medium, and Marco Polo was there from the very first issue, sharing those iconic pages with the likes of Superman, Zatara, and Tex Thomson. With two key-issue appearances to their name and a catalog presence stretching across an extraordinary 88 years, this is a character whose longevity quietly speaks for itself. For collectors who love the deep history of DC's earliest days, Marco Polo is a fascinating thread woven into the very fabric of comics' origin story.
