arch was symbolic of a "buoyant spirit: a feeling of skyward momentum, symbolic of an aerospace age in which man could hurtle himself into the heavens." Langdon goes on to state that the purpose of the McDonald's arch was to bring a sense of structural modernism in a roadside hamburger stand. Historic significance The U.S. National Register of Historic Places added the Pine Bluff McDonald's sign to its listings on August 21, 2006, as McDonald's Store #433 Sign. McDonald's has used a variety of designs for its signs; consequently, early examples are exceedingly rare. The sign in Pine Bluff, Arkansas' only known surviving example of an early single arch McDonald's sign, is also a good example of a rare early backlit plastic sign. Backlit plastic signs were popularized post-World War II and revolutionized the sign industry through the 1950s and 60s. It remains unclear exactly how many single-arch McDonald's signs remain nationwide. Before Hurricane Katrina in 2005, one was still in use in Biloxi, Mississippi. The store on MacArthur Boulevard in Springfield, Illinois, also had a single arch up until 2006. Others exist in Magnolia, New Jersey; Green Bay, Wisconsin; St Clair Shores, Michigan; Warren, Michigan; Montrose, Colorado; Independence, Missouri; Winter Haven, Florida; Belleville, Illinois; and Muncie, Indiana. A sign is also on display in The Henry Ford museum in Dearborn, Michigan. The sign in Pine Bluff is the only such sign that has its own listing on the National Register, though a few others may exist as contributing properties within historic districts. It is likely that most single-arch signs were incorporated into private collections.
