I love this cover, but I always think the villain in the story is the Getaway Genius, who does not even appear in the tale. Detective 364 (June 1967) has art by Sheldon Moldoff and Joe Giella.
The Riddler opens this tale, getting taken down by Batman and Robin. They discover a mysterious clue, not from him, and continue to find these at the sites of other crimes.
Moldoff is not up to par at all on this issue. Aunt Harriet looks about 20 years older, and the Batmobile is an ugly version of the tv car.
The story isn’t that great, either. It wanders, and then concludes with the villain being a sleepwalking Alfred, partly under the control of the Outsider.
I do love the cover, though.
