Part of a series that Dadamaino executed between 1958 and 1960, the work consists of a stretched canvas, painted in white tempera, into which two large oval holes have been cut. The works part of the series Volume were executed mainly either in black – which are the most numerous – or white. Some coloured canvases were also made. The holes vary in shape and size and also in how they are spaced within the canvas. Dadamaino wanted to emphasise the material absence of the work, rather than its presence. In this sense her work relates to the contemporary experimentations of fellow Italian artist Lucio Fontana.
