Blaze Comics Billboard – Man of Steel

It almost takes Superman's power of micro-vision to catch this blink-or-you'll-miss-it Easter egg, but if you look for it, it's there. A Blaze Comics billboard is scene in the background during one shot of Superman and General Zod's climactic fight, which hardcore fans immediately recognized as a nod toward DC's resident time-travelling rogue. Created by Dan Jurgens in 1986, Blaze Comics is a fictional comic book company within the DC Comics universe, which regularly featured Booster Gold as its main hero. Unfortunately, there's no telling if the billboard proves that Booster Gold exists in the DC Cinematic Universe or if some visual effects artist is just a card-carrying member of the hero's fan club.
