The production of this book has been a labour of love and would never have seen the light of day if it hadn’t been for a legion of family and friends who offered their support when I needed it. It would require a small book in itself to thank all the staff at the museums, art galleries, collections and libraries who responded with such invaluable assistance and unfailing good humour to the barrage of requests for information and clarification over the last few years, but sincere thanks to you all. I am also very pleased to acknowledge the unwavering encouragement and astonishing expertise of the editors of New Holland, particularly Julia Shone and Aruna Vasudevan.
