According to ananova.com on this day in 1961 Henri Matisse’s painting ‘Le Mateau’ attracted big crowds when it went on show in the Museum of Modern Art in New York. It was not until 116,000 people had seen it, 46 days later, that someone noticed that it was hanging upside down.

I say it’s a great painting if it looks as good upside down as right side up! My father told me a similar story when I was a little boy. The company where he worked as an industrial designer had acquired a modern painting and hung it in their entrance hall. Years went by until for one reason or another the famous artist visited the company. He calmly pointed out that the painting was hanging on its side.
