The Eli Bridge Company manufactures Ferris Wheels and other amusement park rides, such as the Scrambler. The company was founded by William Eli "W.E." Sullivan (1861-1932) in 1906. Most of this collection consists of a trade journal on carnival rides and devices dating between 1916 and 1935. The monthly magazine was first titled The Optimist, and later continued as Big Eli News. It featured articles about amusement park rides, parts, and operations, and included advertisements and illustrations.
