NEW YORK—An American censor has censored a child's drawing of a cow. A three-year-old Cincinnati girl sent the drawing to her father, an army captain, stationed at Panama.
The censor returned the drawing with this note: "It is against military regulations to mail outside the continental limits of the United States drawings of any public buildings."
