Aside from their 1963 show at the Paris Biennale, aptly titled “Le Labyrinthe,” Groupe de Recherche d’Art Visuel (GRAV) also produced “Une Journée dans la Rue” in 1966. As shown in the map (link below), the artists constructed a variety of activities meant to interrupt the daily commute of a Parisian walking the streets in specific locations, spanning from Metro exits to parks. These activities not only allowed engagement with art in the everyday, it also restructured the regular social interactions of its participants.
