And, dredging up a old thread: I said earlier that I thought the reason Green Arrow and Aquaman survived when others didn't came down to the Adventure/ More Fun content shift. Looking at that now, I think they decided on the contents first, and only after the fact swapped the titles. My current suspected order is they decided to change Adventure to a humor title and brought Dover & Clover over from More Fun to join Genius Jones. Since they then had a slot in More Fun, they moved Shining Knight over as the best feature. Only then did they realize the titles sounded backwards and swapped them. I'm not sure what features I would keep if I was really looking at both books for the best, but if the plan was originally to make the hero book Adventure I think they would have started with the Adventure features and then add the best from More Fun, not vice versa.
I've just had Adventure Comics on the brain recently, what with the revival coming soon. Picked up a few fun pre-code issues, including 161 with a Frazetta Shining Knight. Beautiful stuff, I would love a collection of Frazetta's DC work.
