Princess of Egypt and Iranian Queen Fawzia Fuad, C. 1939

Captured here: Princess Of Egypt And Iranian Queen Fawzia Fuad, C. 1939. Made around 1939, it is the kind of image that turns a date in a history book into something you can actually see.

The 1930s were shadowed by the Great Depression, which put a quarter of American workers out of a job at its worst point. Yet the same decade produced streamlined trains, record-setting aircraft, grand public works, and a flood of documentary photography as magazines like LIFE sent cameras into everyday America.

Moments like this one were captured by photographers who often had a single chance to get the shot — no second takes, no digital preview. That is part of why these frames carry such weight: each one is a split second of real history, fixed for good.
