Quote from the serialpaintings website:

Each one made one day in the subway the experiment of the glance of the other. I would like to remember me all these anonymous faces and their glances. This is why, daily, I paint on a ticket my neighbour in the wagon . This project began with the autumn 2004. It is a painting under colour and format, vibration, time constraints. These painted faces appear always inaccurate. I endeavour to have the memory of the people met, but in the long term the lapse of memory overrides the memory and painting gains: it only remains.

Send him tickets from your city's subway !
