I've got a couple for you. These are Type B, NEMA 5–15. The 5–15 outlet is standard in all of North America. It is also used in Central America, the Caribbean, northern South America, Japan, Taiwan and Saudi Arabia. The 15 means it is rated for 15 amperes at 125 volts. Canon 7D, 1/160 sec @ f/2.8, ISO 800, 50mm prime lens.
From 365 Project The Air Force Memorial in glows against low hanging clouds and mist. Located on a promontory in Arlington, Virginia, overlooking the Pentagon and adjacent to Arlington Cemetery, the memorial's three 270 feet tall stainless arcs evoke the spirit of flight. Taken with a Canon 40D, 5.0s exposure at f/8.0, ISO 200, 28mm equivalent focal length, mounted on a tripod.
This is a reproduction on an early 20th Century "squirrel cage" carbon filament light bulb built by Thomas Edison. In today's modern reproductions the filaments are made of tungsten, which burns three times brighter than the original carbon filament versions. They are really getting popular in vintage bare blub fixtures. This one was hanging over my table at Tarrant's Cafe , 1 W. Broad Street in Richmond Virginia. Canon G15, 1/15 sec @ f/8.0, ISO 200, in macro mode.
