Yesterday I mentioned Piero Manzoni and his tinned "Merda". Earlier this year, there were suggestions that the whole thing might have been a hoax. No shit? But of course, no-one who has paid $45,000 for a tin (or even $168,000) would actually open it to find out, would they?
One pair of artists who have used their own excrement, as well as blood, urine and semen are British-based Gilbert and George (be careful if you're at work and you follow any of the links at the bottom of the Wiki page - you have been warned!).
And then there's Marc Quinn. He made a sculpture of his own head using 8 pints of his own blood. Now that is worth paying for, in the sense that it is valuable - not that I would want to own something that creepy!
What a Waste!
You'll be glad to know that the pictured tin, part of my personal collection, is not for sale.
