A Selection of 150 concept spaziale…

Do you know that canvas you see in every permanent collection in every art museum around the world that has been slashed by an artist called Fontana? There are many of them, each a slightly different size, with a different length slash. When encountering them I peer through the slash to the dark shadow, ‘concetto spaziale’, adjusting my eyes to the light that reaches the gallery wall.
I wonder how many canvasses Fontana slashed, and how they would look displayed from the longest to the shortest? The book aligns and extends these voids from page 1 to page 150.
