1957
January 2-12: beginning of the Blue Period.
Yves Klein exhibited Proposte monocrome, epoca blu, at the Apollinaire gallery in Milan. Eleven works of identical format (78 x 56 cm), uniformly painted in ultramarine blue, were hung by a system of brackets at a distance of 20 cm from the wall, saturating the limited space of the small gallery. Because the blue panels were not framed, the color covered the outside edges of the chassis. For the first time, Klein presented an entire room of blue monochromes, one of which was purchased by Lucio Fontana.
