Apparently, when he was a (smaller) kid, fictional fanboy and all-around, all-purpose Marvel sidekick, Rick Jones, found a barrel full of old comic books that he read until they fell apart (Avengers #92, 1972). And, apparently, in addition to old Marvel standbys like Captain America, Sub-Mariner, and Human Torch, Rick Jones was a fan of the Green Lama -- or at least Rick Jones's floating, glowing head was a fan of the Green Lama:
See? There's the Lama, right there in the lower right-hand corner! And in the opposite corner is the Fighting Yank. Well, waddaya know!
Reckon Rick Jones is reading Project Superpowers these days? ;-)
