Hey guys... I am a professor of music doing research into Peter J. Wilhousky. He was a choral director. He conducted the NY Civil Service Choir for the 1939 World's Fair. Does anyone have an information on him and his connection to the WF? He might have prepared choirs for other WF events as well. I know there is a postcard with a man conducting in front of a very large audience. Does anyone know who that conductor is in that postcard? Thanks for any and all info.
