This is a collectiob of stories from Galaxy magazine which tend to be on the lighter side of sf in its day. My favorite is "License to Steal" in which an alien from a planet where stealing is legal overhears the Terran expression "license to steal' and requests such a license from a local policeman, who writes him one as a joke, but the alien promptly steals the entire New Chicago Merchandise Mart with 20,000 people. The situation spirals out of control from there. Another story involves a time traveling salesman who sells a brick-making matter duplicator to a Sumerian king, and another an alien statistician drafted into the conquest of Earth.Another story involves two rivals trading off an unwanted bossy wife by time machine. Another involves a revenue agent investigating a corrupt ruthless corporation who finds himself aided by an alien inside himself. ( )
