Conan in the jet age?
Are you sure it was not for a 'Thunder Agents' Book?
Well it was most definitely used as a cover for the RBCC. Could have been left from an unused project but doesn't really look like a T.H.U.N.D.E.R. Agents. Timing would be right though so who knows?
Funny, I asked Wood about this cover also. It was during a visit to his New Haven, CT home and studio in late 1978. I was always struck by the nonsense of having a barbarian attacking a jet. Wood told me he had an unused cover rough with a BEM in place of the barbarian that was never used. Does anyone have that art? or did Wood ink over his pencil? If the art is out there, check to see if there are erased pencils of a BEM. AS to why a barbarian - Wood told me that (and here I don't rememember who he said but probably GB Love or Jim Van hise, whoever was in charge of RBCC at the time)he was asked specifically for a Conan (or barbarian - my memory is foggy over 35 years later) cover and since he had this one laying around he made it a Conan/barbarian cover. So that's why we've got such a weird mixture of genres. Richard Pryor
