Here's a big laugh courtesy of John Byrne, from The Comic Reader 143, circa 1977. It was around this period when Iron Fist was set to become Luke Cage's best buddy--and share the masthead when Power Man was re-titled Power Man and Iron Fist with issue #50. Claremont and Byrne were the creators behind this odd couple pairing.
The signature reads: John Byrne, from an idea by Roger Stern, with apologies to Don Martin. Don Martin was one of the premiere artists from Mad Magazine, who drew funny characters with elongated features. Why not take a visit to the Don Martin Shrine today? Nuff Said!
