Though comic books and super heroes have been a part of the American landscape since the late 1930's it has really been in the last 40 years or so that these same comics and heroes have been elevated to a higher status in America's pop culture.
With the cosmic artwork of Jack Kirby and Steve Ditko of early to mid 60's Marvel comics, the underground acid culture adapted comics as their own. The heroes began making their way into the blown minds of a counter-culture that would soon become the main-stream.
Not only Marvel but DC characters too became enmeshed with pop art and popular culture and rock music and comics began a marriage that is even stronger today.
