One Panel #753: Leap Year!

From Superman: "Design of Doom" by Jerry Siegel, John Sikela and George Roussos, Action Comics #56 (January 1943)

I'm a little bit surprised that in late 1942, Superman is still just leaping and not flying. Or he may be flying - I mean, from Metropolis to Africa isn't exactly a "tall building" - but is at least drawn like he's doing a free jump.

Anyway, it's February 29th, allegedly Superman's birthday. That bonus day you get every 4 years. Do something you never have time for.
