“New York City 1 (After Mondrian)”
For 75 years, the Mondrian painting “New York City I” (a grid of red, yellow, blue, and black linear adhesive tapes) was hung upside down. Research eventually proved that it should be shown the other way around. However, due to possible damage, the painting would continue to be displayed the wrong end up. “If you were to turn it upside down now, gravity would pull it into another direction. And it’s now part of the work’s story,” said curator Meyer-Büser in 2022. “Once I pointed it out to the other curators, we realised it was very obvious” (italics mine):
“New York City 1” (Mondrian): Left: right; Right: wrong
Georg Baselitz is famous for exhibiting his paintings upside-down — or rather, right-side up, but with the subject matter inverted — to create unease and/or to make the content more difficult to interpret. His first inverted painting was in 1969, “The Wood on Its Head”. Flipping a traditional landscape of a tree made the work overcome representation, its artificiality highlighted, and left-brain analysis of it disrupted. The subject of the art was not as important as the work’s visual insight. It is immediately obvious that the tree, or in later works, the human being, is not the right way up. Genius, or gimmick? Bravado, or branding?

Rodney Graham is well-known for his photographs of trees hung upside down. (This presentation method evolved from his use of camera obscura, where a pinhole in a wall is used to isolate and cast the image —upside down and reversed, because light travels in a straight line — at large scale onto a facing wall). Of these works Graham said “I was also using a kind of readymade strategy based on the disputable assumption that a photograph is not art but an upside down photo is.”
