Earlier this year I saw an advertisement poster for the Darmstädter photo exhibition 'Bildspuren Unruhige Gegenwarten 2012' (pdf, german) in my underground station.
I was immediately fascinated by the expression on his face.
It took a while to find (the above linked pdf) for a reference - the cover page is the same as the ad.
beyond all thoughts of praise this is truly incredible funny how pictures and objects seem to find the artist sometimes you were meant to draw this , stunning
