The Unicorn Fantasy Fiction series was an attempt by George Allen & Unwin to bring some focus to their Unwin Paperbacks imprint by publishing a line of new and reprinted fantasy novels as B-format trade paperbacks. The series used a distinctive frame design on the cover, with the Unicorn device at the head and cover illustrations by well-regarded artists including Roger and Linda Garland, Les Edwards, Terry Oakes and Steve Weston. In its later years Unicorn drifted away from the striking design that had set it apart in 1982 and also began to issue some of its titles as A-format mass-market paperbacks before it was dropped in 1987.
