Fontana will be represented by a focused survey of his nearly five - decade career, spanning his earliest Spatial Concepts, in which small canvases evoke immense galaxies through swirling fields of paint subtly embedded with small stones and broken glass, to his famous Attessi, or cuts, in which the artist has used a sharp knife to literally slice through the canvas surface into another space.
