The campaign uses 661 200x195mm vinyl tiles featuring the lead, played by Robert Downey Junior, that have been placed in a chequered pattern between the existing wall tiles, which show a profile of the world-famous detective.
Printing was managed by CBS Outdoor and the tiles were printed on a Durst Rho 160 using London Underground fire-rated vinyl.
The campaign, which was managed by Kinetic, is supported by 96-sheet and six-sheet national posters.
