The Flushing Main Post Office is architecturally significant as one of the largest and finest examples of a Colonial Revival style post office building erected in New York State during the Great Depression. The sophisticated Colonial Revival style structure illustrates the popularity of this design mode, which had become the most popular style for federal buidlings in the 1920s and 1930s.

The building, designed and erected between 1932 and 1934, was the work of the prestigious New York architect Dwight James Baum and his partner on this project, William W. Knowles. For this commission, Baum and Knowles served as consulting architects to the Office of the Supervising Architect of the Treasury, under the direction of James A. Wetmore.

The building is the most distinguished of the Colonial Revival post offices erected in New York City during the 1930s, one of the most prolific periods of post office construction in the nation’s history. Although its design stands out among the post offices of the period, the Flushing Post Office exhibits many of the characteristics that typify post office construction of the 1930s, including a symmetrical principal facade with central entrance, steel frame and masonry construction with brick facades, simple decoration in stone and brick, multi-paned window sash, a standardized floor plan with public lobby at the front, and a general high quality of construction. However, the architects were able to bring an elegance of design and materials to the building as reflected in the extensive use of white marble, the sophisticated Ionic portico and elaborate marble interior finishes.

In addition to its architectural significance, the Flushing Post Office contains an artistically significant mural which runs around the entire lobby. This mural was commissioned by the Public Works of Art Program from Vincent Aderente and executed in 1933-4.
