Trier streeatart roundup

I'm still in Amsterdam today, which is a good opportunity for me to finally schedule a post with these pictures of streetart I found in Trier, Germany at Chrismas. The top two ones in particular are brill - they were whole electricity boxes spraypained in their entirety. The Angela Merkel one refers to the grey men in the novel Momo. And does anyone recognise the face on the side of the house? I'm sure i do, but I have no idea where from!
