I read about this poster's existence before I actually got a glimpse of it some years ago here.
It's a dandy promotional piece and Joe Staton's original version of E-Man. Robert Redford's likeness is very evident in the promotional image. The poster pose was of course used on all but the last of the covers in the corner just beneath the classic Charlton Bullseye emblem.
It's a gem and one of those arcane items I never expected to see in the real world, let alone own. But hopefully if the gods smile, I'll be getting one in the mail soon. I just found one online and placed the order. So here's hoping it goes smoothly and soon, very soon, I'll have this early version of Alec Tronn smiling down upon me in my very own house.
