I was a bit jolted in 1972 to see Gardner Fox, a writer who was a centerpiece at DC, who almost singlehandedly established the DC stable of characters like FLASH, JLA, Adam Strange, Kid Flash, Elongated Man, HAWKMAN, THE ATOM, GREEN LANTERN, etc., and suddenly he was over at Marvel doing books like TOMB OF DRACULA issues 4 and 5, and MARVEL PREMIERE 3 or 4 with Doctor Strange. And then he was quietly just completely gone from the comics scene.

I never really saw an explanation of that anywhere, until COMIC BOOK ARTIST had interviews on the subject in the 1990's. That the writers and artists who asked for just a few crumbs more (health insurance, a modest living-wage page rates) were completely, but quietly, shut out and forced to leave in 1969-1970.
