I went to Berlin earlier this year I accidently bumped into Johan Potma at a market by the river Spree, an artist then unknown to me. I bought a copy of this painting, entitled 'Where you live', off him, and now it sits pride of place in my room. Johan is a Dutch painter and illustrator who lives and works in Berlin. He paints with acrylics largely on old wooden surfaces like box lids, signs and cigar boxes. The used materials tell part of the story through the stains, old nails, dents and cracks; the remainder is explained through all sorts of monsters, freaks and oddballs acting out his ideas.
If you like this I implore you to have a look at his website below, as you can still probably get some originals for cheap!!
Also have a look at Mateo Dinnen who works on the stall with Johan, his artwork is of a similar vein
