The historic telephone building at 931 14th St, Denver, CO, as it appeared in August 1929 The Telecommunications History Group (THG) hosts the Telecommunications Virtual Museum. We maintain and operate one of the nation's largest privately held telecommunications archives, two small museums in Denver, Colorado and The Museum of Communications (formerly known as the Vintage Telephone Equipment Museum) in Seattle, Washington. Together, they comprise a permanent collective memory of the telecommunications industry, dedicated to preserving the history of the industry and to telling the stories behind the history.

We conduct educational programs on telephone history, offer tours of our museums and of the historic telephone building at 931 14th St. in Denver, and perform research services.

The Seattle Museum contains exhibits from 1876, starting with a model of Alexander Graham Bell's first successful creation of a telephone, to the modern cell phone that we all take for granted today. Automated displays and special exhibits permit your hands-on participation. Our museum exhibits are unique and virtually all the equipment is currently operational. The Museum of Communications is visited by people from all over the world and may well be the best museum of its type in the world.

Our Archives collection consists of:

British Post Office Call Box Model K-6 We also publish a quarterly newsletter called Dial-Log, available with each $25 membership, by mail, or through our main website.

An Allen True Mural in the inner 931 14th St. lobby.Why is it important to maintain these resources?

Besides preserving and celebrating the history of one of America's most dynamic and interesting industries, THG maintains these documents and artifacts to communicate the political, social and cultural values of recent and not-so-recent eras, with the belief that long-term memory enhances decision making and planning and provides historical perspective. These materials are a source for understanding and identification with society, the telecommunications industry, and ourselves. In addition, we maintain evidence of continuing rights & obligations.
