The London art collector Anthony d’Offay’s copy of the catalogue raisonné of Andy Warhol’s work compiled by Rainer Crone (1970), the cover of which was signed by Warhol in 1986. The cover image, chosen by Crone and Warhol, is the copy of Warhol’s Red Self Portrait (1965) that he dedicated to its then owner, the art dealer Bruno Bischofberger, with the inscription ‘To Bruno B Andy Warhol 1969.’ The picture is now owned by d’Offay.
