This is an invitation for Alexander Graham Bell to participate in AT&T's formal opening of the transcontinental telephone line on January 25, 1915. The event included a telephone conversation between Bell in New York and his old assistant, Thomas Watson, in San Francisco, as well as speeches by President Woodrow Wilson from the White House and AT&T President Theodore Vail from Georgia. When a duplicate of an 1876 telephone was connected to the New York line, Bell, echoing his famous words on the original occasion, called out, "Mr. Watson, come here, I want you." Watson replied that this time it would take him a week to do so.
