Design: The label name lettering is hand-drawn, and optically adjusted to fill the space created as the main strokes radiate outward from the spindle hole (also probably why a horseshoe shape was used for the cap A, instead of the usual triangular frame). Judging from the design, Ultraphon was a stable-mate of the Supraphon label.
History: Label scan courtesy of collector Dimitar Malchev of Bulgaria. Musicologist and collector Bill Dean-Myatt of the U.K. writes: "Ultraphon was a German company that was owned by Küchenmeister of Holland. In 1929 its Czechoslovakian operations were taken over by a Czech company, Ravitas, but in 1945 the label was nationalized and disappeared from the market [although according to Czech collector 'Johnny,' who has the last Ultraphon issue, the label existed between 1930 and 1948]. There were separate French and German companies." Thanks also to collector Gabriel Gössel of Czechoslovakia, who supplied the images below, and adds: "In Germany, the Ultraphon label was eventually transformed into Telefunken. The brown colour label [below] was used for language courses and pressings for Austria, 1932."
