Superman 1939 #257 - 2.0 - $3.00

Superman protecting two kids while War-Horn lurks beneath them.

The Guardians of the Universe explain to Green Lantern Tomar-Re that his failure to prevent the destruction of Krypton might not truly be considered a failure, even though the Guardians once thought to make Kal-El the leader of the Green Lantern Corps, because the destruction of Krypton allowed Superman to fulfill his destiny as the universe's greatest champion.
