Batman and Superman meet the JSA

However, if it was never canceled, then we would had never gotten the Silver Age Flash and Green Lantern or Earth-2.

Yeah, I knew pretty much of that, Michael, but I was talking about when they'd decided to cancel the book.  I'm wondering if Superman and Batman's FULL-TIME inclusion could've saved the book? 

Flash and Green Lantern had had their own books when they came back to the team.  Then, too, heroes like Aquaman, Green Arrow, Vigilante, Congo Bill, and Robotman only had one eight-page strip in Action and Adventure Comics.  If THEY'D been included, too (perhaps substituting for other heroes), might that not have helped the book? 

I honestly don't think so.  Considering how super-heroes were on such a decline at that point I don't think anything could have saved it.  The book was turned into a western.  I think that pretty much says it all.

Also, addressing Gernot's post, I think familiarity is/was key... overrunning a book with superhero characters gets to be a mess, at least for me a 41 year old man, let alone a 10 year old kid in the '40's
