One of the most remarkable productions of the Silver Age, the United Music Corporation, came up with a line of four models in the late fifties. The first two models, the UPA-100 and UPB-100, and the carousel mechanism and finally the design for the Ultra Compact Wall-Box resulted in four patents by Lyndon A. Durant. Raymond Loewy is often related to the design of the United series, but the correct name on the patents is Lyndon A. Durant. The industrial design legend Raymond Loewy was one of the architects of the American Streamline Movement, and his style surely influenced the design of the United jukeboxes. The models, UPA-100, UPB-100, UPC-100, and UPD-100, produced from 1957 until 1961 never became a success, as they were almost unrivalled in the capacity to radiate absolutely nothing, and the Seeburg Corporation finally bought up the company in 1964 (also taking over the Williams company).
