This interior is one of a series of modernistic interiors created for the midtown skyscrapers of the 1920s. It was designed in the same spirit as the building’s exterior: simplicity of detail, long unbroken lines, and beautiful materials.

Because of its size the interior was divided into two portions: an entrance lobby at Fifth Avenue and long corridor lobbies encompassing the elevator banks. The Fifth Avenue lobby, arranged as a long hall focusing on a modernistic aluminum silhouette of the Empire State Building on the far wall, symbolically welcomes visitors, while the corridors, elevator banks, and inner store entrances and windows create a sense of a grand concourse, suggestive of the enormous office building housing a working population of many thousands. Among its striking details are the aluminum silhouettes in the Fifth Avenue entrance lobby, the aluminum mezzanine bridges in the corridors, the silhouetted elevator doors, the ribbed marble walls, and the zig-zag ribbed ceilings.
