Superman #159

From 1963, this DC gem presents an "Imaginary Novel" premise right on its Curt Swan and George Klein cover: what if Earth had exploded instead of Krypton, and Lois Lane had been rocketed to safety? The cover depicts a red-costumed Supermaid Lois soaring confidently above a gleaming Kryptonian cityscape while two Kryptonian men — one in green and gold, one in a familiar blue and red — look on, with speech bubbles making the alternate-history stakes delightfully clear. Ed Hamilton's story promises a fun, imaginative "what might have been" that captures the Silver Age at its most charmingly audacious.
