I saw this being painted by this team of artists(?) on a wall along the Canal Saint-Martin, a neighborhood of Paris in which it appears that graffiti is prized as an art form, or a representation of individual expression, or something like that. Anyway, it (graffiti, that is) seems to be everywhere in this quartier.
If the mural is self-explanatory, do let me know, because I have no idea. It's a fun neighborhood (more about it in another post), so I guess I better go back there to see it finished.
