Falcon

A true relic of Marvel's earliest days, this Falcon soared onto the scene in 1940's Daring Mystery Comics #5 — a Golden Age original brought to life by Bud Sagendorf during the genre's most electrifying era. Sharing pages with luminaries like The Fiery Mask, Thomas Raymond, and The Marvel Boy, this character rubbed shoulders with some of the most colorful figures of wartime comics. With appearances spanning an impressive arc from 1940 all the way to 2010 and a collector-recognized key issue to their name, this Falcon is a rare thread connecting Marvel's pulpy Golden Age roots to the modern era. Five appearances may be a slim catalog, but for fans who love hunting the origins of the Marvel universe, this is exactly the kind of hidden gem worth chasing down.
