Beverly Wysocki, at top, and Marie Graskamp, at side, emerge from a new family-type bomb shelter on display in Milwaukee, Wis., Sept. 12, 1958. The shelter was designed by Thomas Villa, a Milwaukee architect. It is 8 feet by 8 feet by 14 feet 8 inches high, and can hold 8 to 12 persons in an emergency. It can be buried in the earth for added protection. Covered with three feet of earth, it is said that the shelter would be safe to within three quarters of a mile of ground zero if a 20 megaton nuclear bomb were to be dropped. Filters can be installed to make the air inside safe.
