Three Derby racecards, for 1929 won by Trigo, 1931 (punch-holed) won by Cameronian, and 1932 won by April The Fifth The Epsom printers Dorling's appear to have lost their exclusive contract with the racecourse between 1930 and 1933, the cards being printed instead by Knapp, Drewett & Sons Ltd., Kingston-upon-Thames. However, in 1934 Dorling's were back in the 'box seat.'
