Great cover art by Gil Kane and Mike Esposito on this 1975 issue of Captain America and The Falcon. I'm a big fan of the art in general in this issue, I love the way Frank Robbins draws the human body, his poses within the panels sit very comfortably. I also like how many comics get away with using just flat colours for backgrounds within the panels... Visually pleasing or just a bit lazy?
The setup here reveals The Falcon is still comatose after discovering his memories are false implants created by The Red Skull. Captain America is told by a SHIELD psychiatrist that the best way to help him is to beat the living crap out of him! Captain America proceeds to fight a series of hallucinations including; Red Skull, Executioner, Druid, Black Knight, Enchantress, Melter, Radioactive Man and Baron Zemo. The Cap finally breaks free of the mind control and reconciles with The Falcon, it's only then they realise the psychiatrist and most of the SHIELD agents have been possessed by The Deadly Nightshade.
This description on reading it back doesn't seem to make a whole lot of sense I guess, but there is a second part to the story. In the bottom right panel on the last page of this issue it appears that Marvel are aware that the story is somewhat confusing when they say "To be continued next issue -- and maybe we'll even explain all this!".
