Released in the fall of 1973 along with Spider-man Captain America was one the most enduring Marvel characters produced by Mego.
His appearance is not entirely comic accurate, Mego seemed to miss his red gloves and white sleeves. This may have been to due to general expense of producing the figure to begin with. Combining his shield with his already ornate costume probably made it important for Mego to cut some frills to make him cost effective. Every penny can count in production.
Captain America received a lot of respect at Mego, his figure was featured in every WGSH assortment from his inception in 73 until 1982. Mego even issued a Captain Americar in 1976.
The picture above shows the many variations that you encounter when you produce the same figure for nine years (courtesy of Tom).
Above are the two styles of Captain America Window Boxes (note; There is no solid box for Cap) The left shows the early mingled header artwork, Mego chose to use Cap instead of Spiderman for their early headers. On the right is the revised "Marvel Only" header. The back features a swipe from a classic Jack Kirby issue of "Tales of Suspense" read more about it at comic book origins.
Captain America on the early style Kresge card, there is also a variation of this card that only shows the Cap and Spidey on the header. It's interesting to note that these are the only two Marvel heroes that appeared on Kresge cards. This suggests that Kresge cards were produced from 1973 to early 1975.

Mexico's Lili Ledy produced a great example of Cap, there are only 3 boxed examples! courtesy of foreignmego
The Mexicans gave Cap red gloves, smart looking!
Captain America was released via Palitoy in Britain as a Fist Fighter, along with a few other characters that never got the same treatment on the American side. Palitoy also released Cap on a green card but he is one of the more elusive figures in the line.Scan of the Mego Cap FF card courtesy Brain
