Private Mitchie M. Miyamoto, U.S. Army. "Second only to Walt Disney"--that's what the Nineth Armored Division thinks of its cartoonist. He is Private Mitchie M. Miyamoto, twenty-two, an American-born citizen of San Francisco, whose parents are in a Japanese war relocation center. Miyamoto is a "natural" with the drawing pen and ink, and spends his spare time sketching caricatures of his troopmates and officers. He is now on special duty with the public relations section of the Nineth Armored Division
