The synopsis on the jacket reads, in part:"Have you heard of the linotype machine which came alive and made a slave of the printer? Or about the time the earth was surrounded by radio-type waves which cut off electricity and forced people to go back to the horse and buggy days? Or the little boy who beat the Devil with a water pistol? Or of Yehundi, a new type of genie in the bottle, who did anything and everything for his master? Or of the Celestial Compositor who didn't pay attention to his business and who made the life of one earthling very miserable indeed.Fredric Brown tells about these and many other equally intriguing events in this collection which includes both stories of fantasy and science fiction, and some stories that are a mixture of both. But into whatever category they fall, all bear the stamp of the master's far-ranging imagination and zany humor."Originally published in hardback as "Angels and Spaceships."
