Man, those are some very cool redesigns.
Thereâ€™s a lot of history folded into Rafael Grampaâ€™s alternate cover of Detective Comics #50. While that armored Batman is heavily modeled on the one from The Dark Knight Returns, you can also see some small nods to the characterâ€™s Silver Age look, like how the utility belt has capsules instead of pouches.
The Superman costume features more visual cues from the Man of Steelâ€™s history. Thereâ€™s the Silver Age S-shield, yellow piping around the tops of the boots and, my favorite touch, red/yellow highlights at the waist which gestures at both the classic belt-and-briefs combo and the sleeker New 52 version. Gotta love the logo mash-up under the signature on the lower right, too. Great stuff, Rafael!
