A two-color poster reproducing BWS' Conan the Barbarian: Red Nails splash page from Savage Tales #2 (1973).
It was produced sometime in the seventies from the original art.
The lack of any identifying elements has lead to some mystery about the origin of the print. (It may have been produced without the permission of Marvel Comics by the owner of the original art.)
This particular copy was bought in the early 1980s off the wall of a notorious San Francisco secondhand magazine shop.
