Two new images show off the 1978 billboards that advertised Richard Donner's Superman: The Movie upon its release, and they're epic.

The photos come courtesy of Colin Smith on Twitter. The first image shows an artist's rendition of Reeve flying through the air, while the second depicts Clark Kent ripping open his shirt to reveal the Superman suit underneath.

"Sunset Strip billboards for 1978's Superman The Movie," Smith wrote. "The poster featuring Clark Kent's shirt being torn open came first & worked as a teaser. Several weeks later, the image of the flying Superman/Christopher Reeve appeared. (Photographer uncredited.)"

Donner's masterpiece charted a new era for Superman and for superheroes. Also starring Marlon Brando, Gene Hackman and Margot Kidder, Superman was the most expensive film ever made at the time and received high praise, earning itself three Academy Awards nominations. Superman: The Movie's sequel, Superman II, was also positively received, but subsequent installments didn't fare as well.

Reeve starred as the Man of Steel in four films, and later appeared as Dr. Virgil Swann on Smallville. Superman was added to the Library of Congress' National Film Registry in 2017.
