Superman #213 is an issue of the series Superman (Volume 1) with a cover date of January, 1969.

Synopsis for "The Most Dangerous Door in the World!"

Superman sets up a ruse where a supposedly Supermanium safe contains his valuable final gift to mankind, that will only be opened if his heart stops beating. At the same time, Clark Kent runs a series in the Daily Planet detailing the times that Superman has beaten Lex Luthor; angering Luthor.

Luthor takes the bait and steals the safe, using Brainiac's Mole Machine and Shrink Ray. In Metropolis Park, Luthor's giant Kryptonite automatons seem to kill Superman. But the safe — supposedly keyed to Superman's heartbeat — still does not open. Using extremes of heat, cold, and vibration; Luthor finally cracks the vault — and out comes Superman! Flabbergasted by the trick, Luthor's henchmen are slapped unconscious, and Luthor himself faints in disbelief.

Legion villain Mordru had imprisoned Superman in a vault, and magically prevented him from opening it. Supergirl would be drawn inside as well if she attempted to free him. So the Man of Steel concocted an elaborate ruse which, with the help of Supergirl — and Brainiac 5 disguised as Superman — induced Lex Luthor into cracking the vault and liberating him.

They repay Luthor by sending him back to prison.

Synopsis for "The Orphans of Space!"

This story is reprinted from Superman #144.

For the Daily Planet's Centennial, Superman is asked to fly around the world and take pictures of the various Daily Planet offices around the world, he is recognized by everyone and it causes Superman to reflect back on the first day he introduced himself to the world as Superboy:
It all started one day while working in Ma and Pa Kent's grocery store when his x-ray vision spots trouble, Pa Kent decides it's time for Clark to go into action as Superboy for the first time. After putting off Lana Lang with an act of cowardice, Clark changes into Superboy and stops a bunch of scuba-gear wearing crooks and their boss. Revealing himself to the police chief and the mayor of Smallville, Superboy reveals himself and proves that he has super-powers.

When the news goes out that a Superboy exists he soon becomes the center of media attention and asked to aid various government, military, and charity organizations. Superboy soon becomes so inundated with requests that he has to turn them down, opting to patrol the world and put his talents to good use as needed.

With his recollection over, Superman changes back to Clark Kent and meets up with his old high school flame, Lana Lang. The two go over their old class yearbook, and Lana has to laugh when Clark's yearbook profile states that he was the most likely to become famous. Clark finds this funny too, because he has become famous, only as Superman.

Notes

  • The vault in "The Most Dangerous Door in the World!" may or may not have been Supermanium as it was actually made by Mordru, and not Superman. It did survive being heated to 350,000 degrees and then plunged to absolute zero; though its origins were based on magic.

Trivia

  • Superman, in "The Most Dangerous Door in the World!", performs a variation on the stage-magician's trick called the Metamorphosis to deceive Lex Luthor.
