This must have gotten some release in the U.S. in 1992 or later because

I remember seeing in downtown Boston, one of those plywood walls they put around construction sites, was covered in a huge grid of identical posters for a Captain America movie. The poster was mostly just a picture of the shield and the words Captain America. This was after the first Batman but way before the huge glut of comic book movies, so I remember this display had me thinking "this looks like the next big summer blockbuster." and then, nothing. No reviews, no buzz, no merchandise, and later, I remember being told at Blockbuster that they'd never heard of it! When the reboot came out in 2011, I thought, "what about that 'phantom' version I saw the poster for so many years ago?"
