away from the violence of warfare. Leon Garfield and Edward Blishen's retelling of Greek myths, The God Beneath the Sea, which Keeping illustrated in 1970, won the Carnegie Medal for that year. From the later 1960s Keeping, alongside illustrators like Brian Wildsmith and John Burningham, took advantage of advances in printing technology to move from black and white work to adventurous colour techniques. In 1966 he created his first full-colour picture books, Black Dolly and Sean and the Carthorse, both about mistreated working horses. He followed these with Charley, Charlotte and the Golden Canary, a modern fairy tale about two children who grow up in the same street, are separated when one family moves to a new tower block, and are reunited thanks to a pet canary, which depicts the gradual disappearance of the London of Keeping's childhood, a theme he would persistently revisit. The full-colour illustrations are messy and spontaneous, using intense colour, sponge texturing and wax resist, and won Keeping his first Greenaway Medal. Kirkus Reviews concluded a very short review, "Intense colors in striking combinations overwhelm the minimal story." Keeping created 15 full-colour picture books for Oxford University Press, and several for other publishers. Joseph's Yard (1969) and Through the Window (1970), two of his finest, were also produced as short films for the BBC's "Storyline" programme. Through the Window in particular showcases many of Keeping's techniques and themes. Told through the eyes of a small boy watching events in the street outside from his bedroom window, the illustrations are full of intense evening light and colour, movement, and even, when a horse-drawn dray rattles across a double-page spread, virtual sound. Other picture books include Richard (1973), about a day in the life of a police horse; Wasteground Circus (1975), on the transient but magical effect on two young boys of the circus coming to town; and Willie's Fire Engine (1980), a romantic, dreamlike tale of a young Edinburgh boy's dream of being a firefighter. In the 1980s Oxford University Press created a new format for Keeping - the black and white picture book for older children. Keeping created four books in this format: The Highwayman (1981), illustrating the 1906 poem by Alfred Noyes in gruesome detail, for which he won his second Greenaway Medal; Beowulf (1982), adapted from the Anglo-Saxon epic by Kevin Crossley-Holland, in which the illustrations subverted the text with a certain sympathy for
