Back in the late '60s / early '70s, the Warren line of 'creepy' and 'eerie' magazines stood out on the newsstands as something different for 'mature' readers. A degree of violence and nudity had found their way into comics far beyond what the Comics Code Authority would ever have allowed. But being magazines (and the times), young people like me found comics interesting again (at least for a while), and early on thrilled to find Frazetta covers on many of them.
The one interior artist that stood out, for me, with his graceful lines and dynamic compositions was Estaban Maroto, ultimately the only reason I would buy any particular issue, having found the stories themselves usually banal, trite, predictable and boring.
Maroto's art brought sensual design to otherwise lackluster horror.
