The Illustrated Dust Jacket: 1920-1970 (2017) by Martin Salisbury shows how the middle decades of the twentieth century were the golden of the dust jacket, many of which were designed by leading artists and illustrators of the day. It also underlines the impact a cover can have on a reader. There must be many for whom mention of Tom's Midnight Garden (1959) automatically conjures up this first edition cover by Susan Einzig (1922-2009).
