Apparently, this is worth over a million dollars.

Or, rather, it was.

A cleaner with the best intentions accidentally destroyed a piece of art worth more than $1 million when she removed what she thought was a "stain" from the installation. ... The piece of art, titled "When It Starts Dripping From The Ceilings," features a series of wooden planks and a (formerly) discolored plastic bowl. The artist, the late Martin Kippenberger, intended for viewers to understand that the bowl had been discolored by water running over the pieces of wood.

Look, if you need a bowl that's been discolored by water running over it, i've got plenty here at work you can have. It'll only cost you $250,000.
