Crockwell's paintings have been featured in advertisements for Friskies dog food and in a poster for the American Relief for Holland. For the latter, he was awarded a gold medal from the Art Director's Club in 1946.
Posters
Crockwell created recruiting and other posters for various branches of the United States government during World War II, and many illustrations for The Saturday Evening Post.[7]
Federally commissioned murals were produced from 1934 to 1944 in the United States through the Section of Painting and Sculpture, later called the Section of Fine Arts, of the Treasury Department.[9]
Crockwell painted three. In 1937 he completed an oil on canvas mural, Vermont Industries, for the post office in White River Junction, Vermont. In 1938, he completed Endicott, 1901- Excavating for the Ideal Factory, also an oil on canvas, for the post office in Endicott, New York. Signing of the Treaty of Dancing Rabbit Creek was painted in 1944 for the post office in Macon, Mississippi.
Filmmaking
In 1934, Crockwell began experimenting with non-representational films while balancing his career as an illustrator. He initially wanted to create flexible, low-cost animation techniques. In 1936–1937, he collaborated with David Smith, a sculptor, to create surrealistic films.[10]
