Yeah, Chaykin hung out with Wrightson and other new artists for DC, so that was probably influential on Chaykin's style early on. Bruce Jones said that they all recognized that Wrightson's work was the best and most marketable among them, that they loved Wrightson but also envied him for that. And emulated his work to increase their own marketability.

I think that "Judgement Day" story in DETECTIVE 441 was the first story by Chaykin for DC I read. I think the others were his "Beyond the Farthest Star" backup in TARZAN 216, plus the "Iron Wulf" stories in WEIRD WORLDS 8-10, and SWORD OF SORCERY issues 1-4.

Back issues were hard to come by in those days. I never even knew there was such a thing as a comic retail store until 1978. Up till then it was either mail order for back issues, or sometimes if you were lucky, trading missing back issues from friends.
