Need help with a question.

Dont know if this belongs here but will see, can anybody help me with this question
In the Early 60's a museum in New York Acquired and displayed a famous piece of artwork . . . it took them nearly 50 days before they realised something was wrong. What was the artist and name of the artwork, and what was wrong with it?
Cheers.

Ooo ... I heard this one before but don't remember the artist or title of the work. I believe it was one of those abstract paintings of colored squares (partridge family bus type thing). What was wrong? They hung the painting upside-down.

Yeah ... I'm not very good at Double Jeopardy either.
