A nap is a death-defying acrobatic feat for the workmen casually draped across an I-beam above the New York streets. This classic photo by Charles C. Ebbets (1905-1978) chronicles the construction of Rockefeller Center in 1932, Ebbets shot the vertigo-resistant workers from the 69th floor of the GE Building. The adventurous photographer also worked as a pilot, auto racer, wrestler and hunter. His photographic record of American history from the 1920s through the 1970s, encompassing over 300 photos, has been published in countless magazines across the country.
