I just went back and reread issue 109. Like you said, great art. There were a lot of characters, not just Kirbys, whom I think Aparo did the best versions of in that era, including Metal Men, Atom and Flash (arguably Green Arrow as well, but he was basically copying Adams on that front).

Interestingly enough, looking at those scans I see the very next issue, with wildcat, was my first issue as a regular reader of B and B. I still remember picking that one up at the drugstore spinner rack, catchup and taking it home. it’s definitely one of my top all-time Batman issues for that reason.
