The Real Estate Department of Mountain Bell maintained meticulous records, including floor plans and pictures of each building the company owned. The Telecommunications History Group’s Archives contains thousands of these photographs, many of which have been used by preservationists and architects. Below you will find a few photos of the Mountain States Telephone and Telegraph headquarters at 931 14th St., Denver, Colorado.

Built in 1928 and opened in 1929, it is referred to as “The last of the Bell System Palaces“, as it was the last to be built before the stock market crash of 1929 and the subsequent Depression of the 1930s. Our thanks to volunteer, Renee Lang for processing these photos.
