Yellow Pages, in collaboration with advertising agency Rufus Leonard, launched a multi-million pound advertising campaign with London Transport by painting and vinyl-wrapping a six-car C Stock train. The interior seats were also given a unique moquette, featuring lines of Yellow Pages' classification headings. The painted C Stock train was launched at High Street Kensington on 12 February 1998 and ran in service on the Circle line until autumn 1999.
