Caribbean Club- Key Largo, Florida, Circa 1950

The photograph shows Caribbean Club- Key Largo, Florida, circa 1950. Made around 1950, it is the kind of image that turns a date in a history book into something you can actually see.

The 1950s brought a wave of postwar prosperity, especially in North America. Suburbs, television sets, big chrome-trimmed cars, and rock and roll defined the decade, and a booming picture-magazine industry sent photographers to document all of it.

Pictures of ordinary life are some of the most valuable historical documents we have. Grand events were always going to be recorded, but a normal day — how people worked, dressed, shopped, and passed the time — survives only when someone happened to point a camera at it.
