This is the first appearance of Superman’s Fortress of Solitude.

Synopsis:
Superman visits his Fortress of Solitude where he can relax and work on experiments. He discovers a message written on the wall which reveals that an intruder has penetrated the Fortress. Superman seals the entrance, but later learns that the intruder has returned. When a cave-in seals him in a cavern with a Kryptonite rock, Batman appears and reveals himself as the intruder. Superman begins laughing because the Kryptonite is phony. He used the stunt to get Batman to reveal himself. The friends then celebrate the anniversary of Superman’s arrival on Earth.
