BunaB was the name of a line of purposely useless novelty products, promoted as if they were useful via carefully written marketing hype. They were created by American radio host Al Crowder (1904-1981). Beginning in the 1950s BunaBs were purportedly produced by the firm of Orville K. Snav and Associates and distributed from its headquarters in Snav Towers, Mason City, Iowa. The company's chief product was the Improved No. 7 BunaB, an assembly of two 1.75-inch (4.4 cm) insulated wires, red and blue, held together with neatly applied yellow electrical tape at the ends. BunaBs have over time been viewed as examples of primitive conceptual art.
