The winning entry was said to be Queen City."

↑Whelan, Frank (March 13, 2002). "Hamilton Street used to be thick with peanut shells ** And Allentown's Army Camp Crane once had a popular commander". The Morning Call. pp. B.04.. "Allentown's title as the Peanut City goes back to the late 19th and early 20th century when large amounts of them were eaten in the Lehigh Valley. From the 1880s to the 1920s, vendors lined Hamilton Street, singing jingles in Pennsylvania Dutch about the superior quality of their peanuts. Former Call-Chronicle Sunday editor John Y. Kohl recalled in 1967 that the peanuts were eaten mostly by young men and boys who would walk Hamilton Street on Saturday nights flirting with girls and 'throwing the shells about with complete abandon.' Sunday morning sidewalks were 'not quite ankle deep' in shells. Merchants would get up early to sweep them into the gutter so churchgoers would not have to wade through them.'"

"Silk City for example, is a throwback to the late 19th and early 20th century, when Allentown was known for its many silk mills. Although the last mill closed a few years ago, the name hangs on in the minds of older residents."
