This is an excellent Archives volume that actually has a few stories that I don't believe have been reprinted anywhere before (the Atom/Flash, Metal Men/Atom and the Flash/Manhunter from Mars team-ups), so it is probably worth it for a collector to grab this book rather than scrounge for those old B&B issues. The stories themselves are remarkably good, for the most part. The highlights are the 3 Battles Stars (with art by Joe Kubert), the aforementioned Atom/Flash story (with art by Alex Toth) and the first meeting of what would become the Teen Titans in #54, with art by Bruno Premiani. These are classic silver age tales, so don't expect a lot of modern angst in them - just an occasional science lesson. I think the only bad thing about this book is that it is too short; I'd love to have the next three issues (with the Teen Titans, Starman and Black Canary) in this volume.
