This man is outside a dancing show and was imitating the dancers he saw. It is cold and rainy because of the clothes he is raining. I assume it is somewhere in Europe. I think this because of the signs on the building next to him.
Henri Cartier-Bresson was the photographer in 1932. This photo was taken at a railway station in Paris (Gare St. Lazare). He did not expect the image to become so iconic. Bresson’s take on the Gare St. Lazare was completely different from other artist’s views. Decisive moment- captured right when the person jumped. Captured when all the elements just fall into place.
