Vintage double-sided sign for a public telephone, likely associated with the General Telephone and Electronics (GTE) company. The text Public Telephone and General System is prominently displayed alongside a stylized telephone receiver emblem, characteristic of mid-20th-century telecommunications signage. The sign measures 12 inches high by 12 inches wide, with surface chipping present on one edge. This sign was used to identify public payphones linked to the traditional Public Switched Telephone Network (PSTN).
