A historic manhole in Detroit, Michigan, USA, providing access to wiring and controls for the Bell Telephone System. The Bell Telephone Company, named after Alexander Graham Bell, operated most of America's telephone services from its creation in 1877 until it was broken up in 1983 (by which time it was owned by AT&T). The original group was known colloquially as Ma Bell. | |
