VICTOR CONCERT BY WIRELESS
Wurlitzer Co., in Cincinnati, Gives an Election Night Treat to Wireless Operators
CINCINNATI, O., November 3.--Last night the Rudolph Wurlitzer Co. took the opportunity for giving a free concert for amateur wireless operators, using a Victor talking machine for the purpose. Notice of the concert was given several days in advance in order that those who wanted music with their election returns might be prepared to enjoy it. The election returns were flashed from the Westinghouse plant in Pittsburgh and those who tuned their receivers to hear the returns also heard the music, which they greatly enjoyed.
