The Grupo de Arte de Vanguardia de Rosario—created by a fusion of three workshops, with artists from different artistic organizations (alumni from Juan Grela, the Grupo Taller, and recent graduates of the Escuela de Bellas Artes de la Universidad)—initiates its public collective actions and position statements at the end of 1965. Two years later, the group acquires more cohesion and is acknowledged as one of the most dynamic experimental art groups in the country. The Ciclo de Arte Experimental [Experimental Practices of Art Series], planned for the early 1968, began in May inside a space that was given to the group by an advertising agency. A short time later, the Instituto Di Tella from Buenos Aires granted it a subsidy that allowed the group to rent a small glass space inside a commercial gallery. Every two weeks, until October 1968, the group would stage an exhibition proposed by one of its members.
Norberto Puzzolo was the first artist to present his work in the Series, which he did when he was only nineteen years old. The happening he offered consisted of a number of chairs that were arranged to create seating for an audience that would look out on the street, and framed by the window of the gallery. Puzzolo thus created a reversible show: those that attended the exhibition looked out on the street, and the passersby (on the sidewalk) in turn paused to look through the window into the gallery.
