HOW THE HOLIDAY CAME TO BE

DC Entertainment and Warner Bros. established the first Superman Day on June 12, 2013, to mark Superman's 75th anniversary and the theatrical release of the Man of Steel film.

INTRO

Introduction

PHOTO

Superman Day marks the anniversary of a character whose debut in 1938 redefined American popular culture and created the superhero genre as a commercial force. The observance traces back to a single promotional push by DC Entertainment, but the date now anchors a broader annual celebration of Superman's place in comics, film, and global iconography.

Two teenagers in Cleveland, Ohio, invented the character that would generate billions of dollars in media revenue, inspire an entire literary genre, and appear in continuous publication for more than eight decades. Yet Jerry Siegel and Joe Shuster sold all rights to their creation for $130, a sum worth roughly $2,800 today.

ORIGINS

Superman Day history

INTRODUCTION

Superman's origin begins not in a comic book studio but in a teenage bedroom in Cleveland, Ohio. In January 1933, high school student Jerry Siegel wrote a short story called "The Reign of the Superman" for his self-published fanzine, Science Fiction #3. His classmate Joe Shuster illustrated the piece, which depicted a bald villain with telepathic powers, bearing no resemblance to the hero who would follow.

By mid-1933, Siegel had reimagined the character as a heroic figure with a journalist alter ego named Clark Kent. The pair spent the next five years pitching their concept to publishers, collecting rejection after rejection. In March 1938, Detective Comics finally agreed to buy the story for $130, the equivalent of about 13 pages of freelance art rates at the time.

CHAPTER 01

The Birth of a Genre

Action Comics #1 arrived on newsstands with a cover date of June 1938, and its 200,000-copy print run sold out. The issue was an anthology featuring multiple characters, but Superman's 13-page story dominated reader response. Within a year, Superman had his own self-titled series, a newspaper comic strip syndicated by McClure, and a radio serial that would introduce the phrase "truth, justice, and the American way."

The character's success triggered what historians call the Golden Age of Comic Books. Publishers rushed to create competing superheroes, producing Batman, Wonder Woman, Captain America, and Captain Marvel within the next three years. The Fleischer Studios theatrical cartoons, launched in 1941, gave Superman the ability to fly, a change adopted by the comics after animators found his original leaping motion too difficult to draw frame by frame.

CHAPTER 02

From Anniversary to Annual Observance

In 2013, as Superman approached his 75th anniversary, DC Entertainment and Warner Bros. designated June 12 as the inaugural Superman Day. The date aligned with the U.S. premiere of Zack Snyder's Man of Steel and the launch of the Superman Unchained comic series. Warner Bros. unveiled a commemorative 75th-anniversary logo and released an animated short tracing the character's visual evolution.

The city of Cleveland issued its own proclamation recognizing June 12, 2013, as Superman Day, honoring the local roots of the character's creation. The observance continued annually on June 12, and its success prompted DC and Warner Bros. to launch Batman Day in September 2014 using the same promotional model.

How to Celebrate Superman Day

Read the original Action Comics #1 story

The full 13-page Superman debut is available in numerous reprinted editions, including DC's Superman: A Celebration of 75 Years hardcover. Reading the original reveals how different the 1938 Superman was from the modern version, with no flight ability and a much rougher sense of justice.

VISIT

Visit the Superman heritage sites in Cleveland

The house at 10622 Kimberly Avenue in Cleveland, where Jerry Siegel wrote early Superman stories, is listed on the National Register of Historic Places. Glenville High School, where Siegel and Shuster met, and the nearby Siegel and Shuster memorial sign are also worth visiting.

WATCH

Watch the 1940s Fleischer cartoons

The 17 theatrical Superman cartoons produced by Fleischer Studios between 1941 and 1943 are in the public domain and freely available online. These shorts introduced Superman's flight ability and featured groundbreaking rotoscope animation that influenced decades of superhero visual storytelling.

EXPLORE

Explore the Superman Celebration in Metropolis

The town of Metropolis, Illinois hosts an annual Superman Celebration each June, featuring a 15-foot bronze Superman statue, celebrity appearances, and a costume contest. The event has run since 1978 and draws fans from across the country.

WHY THIS DAY MATTERS

Why We Love Superman Day

It created the template for branded character days

The 2013 Superman Day launch became the blueprint for character-specific promotional observances at DC and Warner Bros. Its success directly led to the creation of Batman Day in 2014, establishing a repeatable model that other entertainment franchises have since adopted.

It anchors a character with record-setting value

Action Comics #1, Superman's debut issue, holds the record as the most expensive comic book ever sold at public auction, reaching $6 million for a CGC 8.5 graded copy in April 2024. The issue's original 10-cent cover price has appreciated by a factor of 60 million, reflecting the character's singular place in collectible culture.

It documents the origin of a genre

Superman's 1938 debut directly triggered the creation of the superhero archetype, complete with a costume, secret identity, and moral code. Within three years, his commercial success produced Batman, Wonder Woman, and Captain America, establishing superhero comics as a dominant American storytelling form.
