Publisher profile coming soon
Marvel revolution. Stan Lee, Jack Kirby, and Steve Ditko create the modern superhero. Spider-Man, Fantastic Four, X-Men debut.
The sweet spot for collectors — significant enough to be culturally important, scarce enough to be valuable. 9.8 copies are extremely rare.

Answering an SOS from a boat that has struck an ice berg, the Challengers soon learn that it was a trick by aliens from outer space and are taken prisoner. They are then forces to be exhibits in the Space Circus. Forces to fight gigantic beasts from other planets, the Challengers eventually break free from their cage and free the other captive species and lead a revolt which leads to the eventual capture of the ring master. Taking the ship back to it's home planet, the Challengers turn the ringmaster over to the authorities there before being returned home.

Four hundred million coma victims are found to have been born from October 23 to November 21. Kenn flies home to find his daughter in a coma. Oddly, a topaz birthstone he brought moves to the bosom of a golden king in a drawing. Kenn informs the Challengers the comas may be blocked psychic energy. They order every victim be given a topaz chip on their chest. Atop the biggest topaz deposit in the US, they create a mock topaz-man with Kenn's daughter in the center. As they join hands, power ripples to the topazes on every coma victim. Prince Topaz bursts free, vanishes, and the victims awake.
The Challengers answer a shipwreck distress call, but find it's a trap. They're pulled through space on a light beam and made captives of a rocket ship space circus. The heroes are prodded through cages and catapulted into a tank to fight Quadro, the Four-Finned Demons. Other alien performers are also captives. As the Challengers prepare for a last stand, Prof learns the atmosphere gives them super-strength. They bombard the circus guards with boulders and disable the ships. The aliens are surprised to learn the circus owners are criminals and promise to send all the captives home.
