Earlier this week, we mentioned that Superman had gathered over 4 million likes on his official Facebook page. That’s an astonishing milestone, and we know that it could only have been possible with the support and love for the character fostered by all of you—the awesome Superman fans who have kept our favorite Kryptonian flying high for 75 years.

Over that time, Superman has accomplished much. Along with his self-titled flagship comic, he’s been a part of some amazing ongoing titles like Action Comics, The Adventures of Superman, World’s Finest Comics and the upcoming Superman Unchained. He’s starred in critically acclaimed graphic novels such as All-Star Superman, Superman For All Seasons, Kingdom Come, Superman: Last Son of Krypton and The Death of Superman. He’s appeared on the big screen and small in both animated and live action form, in prose novels and children’s books, on clothing, in videogames… He’s one of the most widely recognized characters in the world, and with the support of fans like you, his popularity will only continue to grow.

We wanted to thank all of you for reading Superman comics, watching Superman movies, and helping to make the Man of Steel one of the world’s most popular super heroes. So for the next 24 hours, we’re offering a free download of Grant Morrison and Rags Morales’ extra-sized ACTION COMICS #1.
