Good Taste in Reading!

In July 1963, the truly with-it type of cat was reading Superman 158, which gave a lot of background information on the bottle city of Kandor, and introduced the names Nightwing and Flamebird to the DC universe.

It was a great three-part novel that featured super-powered guys breaking into Earth's scientific installations, provoking Superman and Jimmy Olsen to go undercover to secretly infiltrate the only possible origin of the super-invaders -- Krypton's original capital, Kandor!
