The 1970s Captain America Adventures

It seemed that, when they weren't having him fight WW2 leftovers, Marvel didn't quite know what to do with a patriotic hero in more cynical times.

So, Captain America did, occasionally, also have adventures that reflected some of the issues facing the United States of America.  This picked up during the 1970s, as  the1960s' civil rights and Vietnam war topics were joined by others, such as women's liberation, .
