Given that 40 years translates out into a lot of comics, and given that the official collectors edition dvds mean that almost all of this backlog is easily available, it's sometimes hard to find the kind of issue you're looking for. Namely, one in which the characters you're interested in actually interact.
To that end, I've tried to create a very simple, extremely informal guide to the comics on the dvd 40 Years Of The Avengers.
In no way are most of these intended as reviews or judgement calls. They're just meant as a way of telling how much Iron Man and Captain America content an issue has - with slight snark thrown in to keep me from getting bored.
NOTE: At this time, this project is incomplete. Avengers vol 1 and 2 remain unaddressed for the present. More forthcoming eventually.
