There's a telly programme I occasionally watch called 'Fake or Fortune'.
It takes a painting, and they try and work out if it can be attributable to a known/respected artist.
The value usually ranges from £500 if it can't be attributed, or £2,000,000 if it can. What makes me laugh is, at the end of the day, it's the same painting, and it's just the signature that's giving it the value, not the composition, quality or technique etc.
Shows the nature of our society, and how easily we can be convinced that an item has a 'value', which makes it desirable to some, and then the value increases further......
