Blue Marvel

A rare find for the dedicated completionist, Blue Marvel made their Marvel Universe entrance in 1992's Quasar #41, brought to life by the legendary Mark Gruenwald and Andy Smith during the Copper Age's fertile period of cosmic expansion. With a catalog presence spanning into the late 2000s, this character has kept some genuinely stellar company — sharing pages with the likes of Wendell Vaughn, Kayla Ballantine, and Captain Marvel across titles as tonally varied as Quasar and Punisher. Appearances this scarce have a way of making collectors sit up and take notice, and with Gruenwald's fingerprints on the debut, there's real pedigree behind even a brief comics existence.
