With the debut of the modern traveling circus in the early 1800s, circus posters became crucial for drawing crowds to what were only one or two performances per location. Many early ads were simple woodblock prints mentioning the name of the circus, the price of admission, and a few acts (often pre-printed images with custom text). Later, in the early 20th century, colorful, fanciful custom designs of leaping animals, clowns, and ringmasters became standard for circus posters.
