I attended a great private auction diner tonight in honour of a nice association (thanks Christophe for the opportunity to attend). Galienni, a French artist that I was happy to recommend to the event did a great performance = painting the work of art live (you can see all pictures of the process on Flickr).
His painting was eventually sold for 2300 euros, almost doubling his last price of 1200€ for one of his paintings at the Drouot auction house. Well done Stéphane!
I'll let him explain the meaning & symbology (beautiful) of the painting on his own blog at http://www.galienni.com.
