Of course Sam can't hold down his own book- he's never been on his own as a superhero beyond a token black character- has he even been given his own limited series?
Falcon did have his own 4 issue limited series in the early 80's! The first issue was drawn by Paul Smith and I think the rest were by mark Bright. It was written by Jim Owsley who would later be known by the name Christopher Priest. The same Christopher Priest who would go on the write great runs on Power Man and Iron Fist, the Ray, and Black Panther.
I only know this because I collected and read it as a kid but it was thrown out along with the rest of my collection at the time by my dad. I just recently found fairly pristine copies of the entire series at Heroes Con in NC this past June. SCORE!!
