The flag of St. Louis, Missouri consists of a solid red background and three thick, wavy lines colored blue and white extending from the top left corner, bottom left corner, and center right edge.

In January 1916, they awarded the winning design to Edward A. Krondl, a young commercial artist.

[4] Krondl's design featured an image of Saint Louis riding on a horse on a blue background, with orange and white stripes extending to the right.

It was later discovered that Krondl had designed this flag as well, but had submitted it under the name of his friend Woehrle because he “wanted to win on merit and not the prestige gained by winning the previous contest.” The aldermen approved the design, but it wasn't until 1946 that the flag was officially recognized by a city ordinance.

Charles Nagel, a St. Louis architect who was particularly critical of the old design, approached Theodore Sizer, an art history professor at Yale University, about constructing a new one.
