Nigel Mansell-signed set of six limited edition racing car prints after David Wilson, each one bearing his ink signature, also signed and numbered 1 / 50 by the artist in pencil, all titled 'The Nigel Mansell Collection' and featuring a car significant in his single-seater racing career between 1981 and 1993: the Lotus types 86, 96T and 97T, Williams FW11B and FW14B, plus the Lola T93 Indycar, 21 by 30cm., 8 by 12in. There is an unconfirmed suggestion that Mansell only signed the prints numbered one in this edition.
