It was after he had been freelancing for a year, and into his run on "Hulk", that David felt that his writing career had cemented. After putting out feelers at DC Comics, and being offered the job of writing a four-issue miniseries of The Phantom by editor Mike Gold, David quit his sales position to write full-time. David had a brief tenure writing Green Lantern when the character was exclusive to the short-lived anthology series "Action Comics Weekly" from issues #608–620 in 1988.
