A series that filled the void, after DC abandoned the Edgar Rice Burroughs adaptations in the first 7 issues. "Iron Wulf" was Chaykin's first series with his own characters.
With a little help from friends like Simonson, Milgrom, Starlin, O'Neil and Alcazar.
Simultaneous with that in 1973, Chaykin was also doing
SWORD OF SORCERY for 5 issues, scripted by O'Neil. A couple issues were inked by "Crusty Bunkers", which was more Neal Adams and less his assistants at that stage.
