The prez also appeared in an issue of Sandman and IIRC he was in a late-80s/early 90's swamp thing annual although I might be thinking of a different 60's style hero there. That's the only place I know him from but he looked hokey enough that I'm not at all suprised he had his own series in the 70's.
My <a href="http://www.superdickery.com/dick/62.html">http://www.superdickery.com/dick/62.html">favorite</a>. You gotta wonder about a media format which feels the need to actually put on the cover 'this is not an imaginary fight scene! Nor a symbolic picture! Nor any other sort of cop-out!'
Reminds me of a cover to X-men in the 90's that said something like "In this issue an X-men dies! REALLY!" The x-men in question was Storm and she was back in like 4 issues. I swear comic book heaven has a revolving door.
