The Gatsby, also known as the Lundberg Stetson, was very popular in Europe and North America in the late 19th and early 20th centuries. It is commonly associated with paper boys and wealthy golfers. It is traditionally a men's cap, but it became popular with affluent women and fashion houses in the early 21st century.
