Three items signed in ballpoint or felt tip by Vint Cerf—an original sketch by Cerf of a diagram of the "Internet, ca. Nov 1977," which details the connection between the "PRNET," the "ARPANET," and the "SATNET," on a white 10.5 x 8.5 sheet of glossy paper; a glossy 8 x 10 photo of Cerf in earlier age in front of a chalkboard; and his personal 3.5 x 2 Google business card. In overall very good to fine condition, with heavy scuffing to the lower left corner area of the sketch.
