This particular cover is notable, I believe, as the first instance where Neal Adams drew Batman. I remember it being very jarring at the time after so many Swan/Klein classic covers.
The interior art is even more jarring by Golden Age Captain Marvel artist Pete Costanza inked by Jack Abel. It's another Cary Bates story but not a good one.
Another good back-up at least.
Loved this ad for the "new" Superman but other than boring new art for a while, this one didn't quite take. It would be a couple more years before Julie Schwartz taking over from Mort would lead to any real change.
