Rather than being a project of a New Deal construction agency, the post office represents a direct relief project of the Treasury Department.  The construction of new post offices allowed the federal government to assist communities through the purchase of materials and the creation of construction jobs.  The project also provided Las Animas with its first purpose-built post office.  The U.S. Treasury Department’s Office of the Supervising Architect under the direction of Louis A. Simon designed the simple, traditional, and restrained building with its high quality materials throughout.  It has been the only post office in Las Animas since it opened in 1938.  The property is associated with the New Deal Resources on Colorado’s Eastern Plains Multiple Property Submission.
