From 1930-1931, pioneering photographer Lewis Hine (1874-1940) documented the building of the Empire State Building in a well-known series of photographs. These postcards feature two favorites, both dramatic. One shows a heater getting bolts red-hot to toss them to riveters. (I still can't believe I sent this off.) The other one I love because of its aerial perspective and even more because of how it frames my favorite building, yes, the beautiful Chrysler.
