It was a two-volume hardback, not a trade paperback, which came in a heavy cardboard slipcase. The slipcase used the actual cover from Captain America Comics #1, not a newly drawn version of that cover (the one in your link looks like Kevin Maguire). I remember holding off on buying it as it was very expensive for the time (like $60-90). I sold the books off years ago, so I can't look up an ISBN or anything.

That book, and the follow-up, is the one you read.

Just a different format. I linked to the V1 TPB at comics.org.

See if this looks a bit more familiar. I think this is the HC set you were talking about.

Same material as the Classic Years SCs, though.
