Before you could take a panorama with an iPhone, they were a big deal. You had to buy special film and get it developed, then the really long photos never fit in those envelopes with the other photos that one hour photo places gave you. In the 1920s and 1930s they were an even bigger deal, and required a lot more effort that resulted in incredible images, many of which ended up in the Library of Congress. Some panoramas from Miami recorded significant events, like the devastation after a hurricane or a big beach party with hundreds and hundreds of people looking right at the camera all at once. Others recorded Miami's important sights, or its beautiful natural environment, and were often used as tourism promotion.
