SirDragonBane posted a review on the new Hasbro U.S. Agent from the Captain America action figure series. Something was familiar about the costume- had Captain America worn a similar costume? Turns out he did, though what exactly happened, who wore what costume, is still somewhat unclear to me... I realize some of you are much more knowledgeable Marvelites than I, so please forgive my "discovery" process :D
From Wikipedia: "During the 1990s, U.S. Agent wore a discarded costume of Steve Rogers, the original Captain America, which was black and had a different alignment of the stars and stripes to differentiate it from Steve Rogers' original Captain America suit design."
"...Soon after, the original Captain America, Steve Rogers, was forced to abandon his costume and identity or blindly serve the U.S. Government Rogers resigned, donning a black costume and called himself the Captain."
