In late 1959 the magazine was sold to Great American Publications, and it was significantly redesigned. The size was increased to that of a glossy magazine, although the magazine was still bound rather than saddle-stapled. Under King-Size Publications, the magazine had had no artwork except small "filler" illustrations; now interior illustrations complementing the stories were introduced, and photographs and diagrams accompanied some of the articles. A fan column, by Belle C. Dietz, began, and Sam Moskowitz wrote two detailed historical articles about proto-sf. However, the March 1960 issue was the last one. Fredric Brown's "The Mind Thing" had begun serialization in that issue; it was eventually published in book form later that year.
