Mountain States Telephone & Telegraph Company Headquarters Building (931 14th Street, Denver, Colorado, 80202, built 1929). Architect: William N. Bowman. 

Built from the finest materials, this commercial building features Art Deco murals depicting the history of communications by famed Colorado artist Allen Tupper True (1881-1955). The architecture blends Art Deco and Gothic Revival, a style designated by the owner as Modern American Perpendicular Gothic due to its soaring height, setbacks and Gothic ornamentation. The building was added to the National Register of Historic Places in 2005. The ornamental light fixtures were designed, manufactured and installed by Albert Sechrist Manufacturing Company. Other local craftsmen include ornamental ironwork by the August Freidrichs Company and display windows by the Frank Kirchhofs American Fixture Company.
