In response to the invitation to my postcard collectors of December 4, 1999, I have received one or more cards from many people: Danielle Arnaud, Ken Arnold, Alexander Brener and Barbara Schurz, Sadie Coles, Robert Collén, Dan Crowe, Claire Fox, Rebecca Hossack, Ian Hunt, Sue Malvern, Giles Prince, Salon de Fleurus, Arnd Schneider, Victor Skipp, Yolanda Sonnabend, Jacques van Alphen, and Helen Wilks. A number of people have sent me postcards, but they appear to have been lost in the mail: Irwin and Eda Cufer, as well as Lynda Morris, who has sent me the entire Francis Bacon series. Some people have stored or sent the cards away because of refurbishment or move: Mary Barone, Keiko Tsutsumi, and Emma Walker. So far, only Christine Vandemoortele has let me know she is not a collector. But what about so many others, among whom I will name but a few: Georg Baselitz, Achille Bonito Oliva, Sophie Calle, Anthony d’Offay, Ronald Feldman, Stephen Friedman, Marian Goodman, Damien Hirst, Jay Jopling, Sarah Kent, Jeff Koons, Catherine Lampert, Sherrie Levine, James Lingwood, Jenny Lomax, Gustav Metzger, Maureen Paley, Giancarlo Politi, Charles Saatchi, Nick Serota, Matthew Slotover? Am I to assume they are not my collectors, either?
