America at night

"This book contains almost 200 photos taken from the late nineteenth century to the 1960s by the General Electric Company. Over these decades GE scientists continually experimented to invent and modify street lights that could transform urban downtowns, rural roads, and parks into daylight use. The images in this book show more than half of America lighting up for the first time liberating the country from common darkness and allowing entertainment, work, and pleasure to become a 24 hour pursuit." -- provided by publisher.
