I found this interesting paper in the Californian Eagle, Feb. 10, 1944, and felt a bit bizarre while reading things like "Mr. Vallier is the only member of the race" or "Brave Heroin of our Race"... Times have changed, fortunately (well, we hope so). Anyway, the Californian Eagle was an Afro-American made and dedicated, based in Los Angeles.
Reading this article, it seems that Mr. Joseph T. Vallier was a real Humanatone afficionado. We also learn that he had worked with Cornelius Coleridge « Dick » Campbell, who was a key figure in black theater during the Harlem Renaissance.
We already know another "Humanatonist" who was programmed on Radio: Mr. Ray C. Clarke.
