It wasn't really the end of Adventure Comics in the golden age. By 1945 or so, paper shortages and changes in comic reader's tastes away from super heroes caused a change at National (DC) Periodicals. Over at "More Fun Comics" the format was changing to a humor format, so the heroes that now inhabited those pages made a mass exodus over to Adventure and teh Adventure Heroes were laid to rest (or at least in Sandman and Starman's cases to their adventures with the Justice Society of America over in All Star Comics.

I'll reserve my look at these later additions to Adventure Comics, when I get to More Fun Comics since that's where they originated...I have to have SOME semblance of order, no matter how loose.
So for now, here are the heroes that made Adventure Comics great.

That's a mess of star power. Those old anthology books with this many heroes (and more fun features) cramming 64 pages of 4 color goodness each and every month for one thin dime must have been pretty awesome!
Meanwhile, back at "Ye Olde Drink Hole"...
