Sky Masters (April 26, 1959) By Jack Kirby and Wallace Wood
Sky Masters was a syndicated newspaper strip and a riff off the Flash Gordon genre. When Joe Simon and Jack Kirby split, Jack teamed up with another writer/artist named Wallace Wood.
One of their first assignments was Sky Masters, which Jack was excited about. Until he read his contract which basically said if the newspapers the strip was in didn’t sell enough he could end up drawing the strip for no or even loose money.
