Another of my favorites, Adams' cover for BATMAN 217, Dec 1969, the story that brought the avenger-of-the-night look to BATMAN as well as DETECTIVE, closing Wayne Manor and the Batcave, and having Batman move into a downtown penthouse, to be closer to the city action and better able to fight crime there.
And Robin goes away to college, making Batman and Robin crimefighting stories much more occasional. It only took the kid 30 years to graduate high school!
