When Eero Saarinen designed the Gateway Arch in 1947 (later finished in 1967), it was unlike any national monument ever seen—particularly in the plains. The stainless steel arch swooped upwards like a giant gleaming frown, cutting a thin and futuristic shape in the sky.

At the time, Saarinen described the arch as richly symbolic of the West. “The major concern, “ he said, “was to create a monument which would have lasting significance and would be a landmark of our time...Neither an obelisk nor a rectangular box nor a dome seemed right on this site or for this purpose. But here, at the edge of the Mississippi River, a great arch did seem right.”

Last year, Gateway Arch became the United States’ 60th national park. To celebrate, Type Hike, a non-profit organization started by graphic designers David Rygiol and James Walker, has sourced a collection of typographic posters designed to honor Saarinen’s famed monument.

The posters are a mix of interpretations, from modernist typography-heavy designs to geometric representations of the arch design. You can vote for—or purchase—your favorite. The winner will be deemed the Type Hike’s official poster for the Gateway Arch National Park. Check out more poster designs below and the full range of submissions right this way.
