Here's a great little done-in-one from Gary Freidrich & John Romita, where Cap & Falc go all relevant and get involved in a race riot in Harlem. ( Sorry, I mean A Holocaust In Harlem! A Tale Of Today! as Gary says... )
You'll know who the bad guy is from the cover onwards, and his master plan really is a bit crap, but then, he didn't really need to be there at all, the story working perfectly well without him.
None of that matters though, as Jazzy John does a great rubbish strewn slum area and makes even the quiet character moments visually exciting.
Yes, the script is as overwrought as every other 'relevant' saga of the time, but that's why I love it, and you can tell Freidrich means well. Plus, there's no easy wrap up at the end, and Cap & Falc even fall out a little bit over their respective sides of the argument.
And I always loved that title logo with the two of them standing there ready for action.
