The wall at Auber was made available to 6 artists for a year, by the RATP:

Madame, Speedy Graphito, YZ, Mademoiselle Maurice, Gilbert1 and Jean Faucheur.

THE WALL created by one of these 6 artists is visible for two months, then covered by the next.

One of the features of this project is the non-use of conventional bombs so the MUR is made of acrylic or water bomb.
