Great Caesar's Ghost! The 21st Century Superman has come a long way since his first appearance in a 1938 comic book. Over the decades, the Man of Steel has gone through several transformations�from the 1950s black and white television "Adventures of Superman" to the 2006 wide-screen, hi-def, special-effects film "Superman Returns."
No matter what version you love best, the Superman logo is still one of the most recognizable images in the world, standing for a super hero who keeps on thrilling hearts and bringing hope to every modern-day Clark Kent and Lois Lane.
