Conceptual art is nothing new and it seems that we all need an occasional attack of the vapours.
Here's Duchamp's 'Fountain' from 1917
Picasso's 'Bull's Head' 1945
 
And Andre's notorious 'Equivalent V!!!' acquired by the Tate in 1972
 
Our Tracey, whilst a talented draughtsman (some exquisite sketches) has become something of a one trick poney which is a great shame.
Personally I am quite happy to go along with the BBC's recent pick of Modern Masters i.e. Matisse, Picasso, Dali and Warhol.
