献给摄友部落的专家们。不过也许你们都看过了。这是从pps格式转来的，也许丢掉了原作的质量。不过还是很惊悚。 ‘ONCE UPON A TIME IN AMERICA’ CIRCA 1930 The photos in this presentation, are real. Some of them are historical photographs and were made by Charles Ebbets in the early 1930’s. Most of them depict daily scenes of the workers who participated in the construction of the skyscrapers between 1920 and 1935. As you will see, the safety measures were somewhat peculiar and the photos were done trying to play down that situation. The author is Charles C. Ebbets. He is one of the more solid photographers of the world. The photographs were taken in New York, on September 29th 1932, and published in the New York Herald Tribune in the Sunday supplement of the Oct. 2nd of that year. It was taken on the 69 floor of the 70 that is the GE building in the Rockefeller Center. Many of these images comprise the Bettmann file, founded by Otto Bettmann in 1936. It contains a collection of 11 million photographs and includes some of the best historical images of the United States. At the present time the file belongs to the Corbis company, property of Bill Gates.
