dropped in 1936 and subsequent editions. Bill Gillies' 1950 cover art shows Nancy watching from a window as Frank Jemmit digs a hole outside. A more simply executed version of this image was used for half of the endpaper used from 1953 to 1959 (known as the 'Digger' endpaper). The endpapers show the digging man, while Nancy (in art adapted from The Secret of Red Gate Farm) hides behind a tree and watches. The 1968 cover art shows a flip-haired Nancy near a candle with Asa glowering in the background. This art was also used as generic cover stock, in red, blue, and pink, for library binding or rebound library copies of all titles in the series.
