The building is listed in the National Register of Historic Places as part of a group of Kansas Post Offices noted for their artwork.

It is representative of the large and cohesive body of architectural work by Louis A. Simon, who was responsible for the design of government buildings at the Office of the Supervising Architect under James A. Wetmore.

The new building provided an anchor for development and helped draw businesses north along Main Street from Douglas Avenue.

While the receding walls of the towers stress the vertical, the long facades of the building express an overall horizontal emphasis.

The main entrances in the towers on the south elevation have heavy molded surrounds, ornamental reveals, and shelf heads.

[2] Stone carving on the exterior-primarily around the entrances and near the tops of the towers-combines classically inspired, Art Deco, and regional motifs such as winged lions, eagles, buffalo, Native Americans, wheat, and ears of corn.

An ornamental band with a stylized, winged-bird motif is centered between the window heads and the cornice line.

The most impressive interior spaces with grand materials remain intact; these include the lobbies, corridors, and courtrooms.

Ward Lockwood and Richard Haines received the commissions through a post office mural project awarded by the U.S. Treasury Department's Painting and Sculpture Section.

Tall corn and sunflower plants frame the center panel of the canvas, in which a farmer on horseback visits his neighbors.

In the distant background, a small town with a railroad depot and grain elevator represent the growing role of industry in agriculture.
