Before the big movies, before the slick animation, and long before the Marvel universe took over theaters, Captain America had his own cartoon segments in 1966 as part of The Marvel Super Heroes.
The animation was pretty limited, often looking like comic book panels brought to life with a little movement and narration, but that was part of its charm. Kids still got Steve Rogers, Bucky, the Red Skull, the shield, and that patriotic theme song that could stick in your head all day.
It may look simple now, but for many fans, this was the first time Captain America really “moved” off the comic book page and onto television.
