A Nation United By Telephone
Colorful map of San Francisco, published as a promotional brochure for The Pacific Telephone and Telegraph Company.
On the verso, the text includes the cost of a 3-minute phone call from San Francisco to various points in the United States, peaking out at $4.00 for a 3-minute "station to station" call to most of the East Coast.
The promotional text also references a Conference Telephone Service for up to six people, including instructions on how to use the service (Just lift the receiver, call or dial long-distance and ask for the Conference Operator . . . Its as easy to use as your regular Long Distance Service).
An inset photograph shows a telephone operator stretching her hands across the entire United States connecting East Coast and West.
