Superman #200

Superman #200 (On Sale: August 3, 1967) sports a cover by Curt Swan and George Klein.

"Super-Brother Against Super-Brother" is by Cary Bates and Wayne Boring and you would think they would have done more for this milestone book than an imaginary story, but they did not.

Prior to Krypton's destruction Brainiac visits the planet. Instead of shrinking Kandor, Brainiac shrinks Kryptonopolis, the home city of Jor-El. Brainiac does so to save the city from Krypton's destruction and is hailed as a hero. However, Brainiac is unable to enlarge the city back to normal size, so the residents remain trapped in the bottle for many years. During that time Jor-El and Lara have another son, Knor-El.

Years later, Brainiac finally discovers a way to enlarge the city. However, a tragic accident occurs, killing Brainiac and leaving the bottled city abandoned on Earth. Enough of Brainiac's rare elements still exist to enlarge one man, so citizens compete for the honor of becoming Earth's Superman. Knor-El wins with Kal-El finishing second.

Knor-El is enlarged to full size and adopts the secret identity as Ken Clarkson, reporter for the Daily Planet. He fights crime as Superman and builds an undersea lair to protect the bottled city. Then aliens invade and hit Knor-El with Kryptonite.
