A fictional superhero in the Marvel Comics universe who first appeared in 1941, during World War II. Captain America is the alter ego of Steve Rogers, a frail young man who was enhanced to the peak of human perfection by an experimental serum in order to aid the U.S. war effort. He wears a costume that bears an American flag motif.
Note: A moment of silence on Patriot Day. Hard to believe that 10 years have passed since the 9/11 attacks. I love this tribute poster from Extra Credit Projects.
