All these photos are real, some even historical, for early 30′s of the past century! The author is Charles Ebbets, one of the construction workers. Most of the pictures shows everyday jobs at the sky-scraper construction, between years 1920 and 1935. You will certainly be able to see that safety at work was, at least odd, but they didn’t mind. Today, these photos, and many others from that time, belong to CORBIS company, which is in possession of Bill Gates.
