Besançon school of fine arts is based on a modernist building by Josep Luis Sert (1972). With Rainer Oldendorf and students, we defined a signage system composed in Garaje 0503 Monospace Black, used for the logotype I designed at the time. Letters were reproduced in 2 sizes, A4 and A6. Rainer Oldendorf and Gilles Picouet engraved litterally the concrete wall of the main entrance, to inscribe physically this 750-units grid on the building. The paper letters were directly stuck on the wall, to announce the events of the school, forming a continuous palimpsest.
