Novelty architecture is a type of architecture in which buildings and other structures are given unusual shapes for purposes such as advertising or to copy other famous buildings without any intention of being authentic. Their size and novelty means that they often serve as landmarks. They are distinct from architectural follies, in that novelty architecture is essentially usable buildings in eccentric form whereas follies are non-usable, ornamental buildings often in eccentric form.
Although earlier examples exist, such as the planned but never completed Elephant of the Bastille, generally the style became popular in the United States and spread to the rest of the world as travel by automobile increased in the 1930s. The Statue of Liberty in New York is a replica building that is part sculpture and part monument, which like many subsequent examples of novelty architecture, has an accessible interior and became a tourist attraction.
Constructing novelty architecture near to roads became one way of attracting motorists to a diner, coffee shop, or roadside attraction, so buildings were constructed in an unusual shape, especially the shape of the things sold there. "Mimic" architecture became a trend, and many roadside coffee shops were built in the shape of giant coffee pots; hot dog stands were built in the shape of giant hot dogs; and fruit stands were built in the shape of oranges or other fruit. Tail o' the Pup, mimics a hot dog-shaped hot dog stand; Brown Derby is a derby-shaped restaurant; Bondurant's Pharmacy is a mortar-and-pestle pharmacy; the Big Apple Restaurant, a 10.7 metres (35 ft) and the Big Duck are respectively a tall apple and a (now defunct) poultry store shaped like a duck.
