I first encountered the GA Captain Marvel (as in the original stories, not a revival) in the Smithsonian Book of Comic Book Comics, and loved it. It was the highlight of the book for young me. But it's a hard thing to get into. I know there were some Archives that I bought back in the day, and I bought and enjoyed them, but the series was not yet what it would become.
I know there have been a few reprints here and there, but have there been any collections of the "golden age" of the Golden Age Marvel Family? Stuff from their heyday?
