Manzoni founded the Gallery Azimuth in Milan in 1959 with the artist Enrico Castellani, and staged a series of revolutionary exhibitions of multiples.
Contemporaneously with the Bodies of Air (Corpi D'Aria), Manzoni produced the Artist's Breaths (Fiato d'Artista), a series of red, white or blue balloons, inflated and attached to a wooden base inscribed "Piero Manzoni- Artist's Breath".
