Fontana is best known for his claim to have introduced elements of time and space into art by slashing the canvas with a razor blade. He also explored other styles and in these and in many statements and manifestos he published Fontana strove to originate new forms of art appropriate to the modern scientific age. Although not slashed this canvas is perforated in places. It is one of the last and largest of a series of 'gessi' or chalks, made between 1954 and 1958. Fontana has written that it 'was painted in an attempt to develop the means of art so as to achieve a contemporary expression'.
