As Big As The First Piece Of Street Art Posted Today,

these ones are so small you might miss them,

 so if you are walking around the streets of of Ann Arbor, Michigan, 

 keep a look out for the work of artist and illustrator David Zinn,

 I have to say some of them like this one are so delightful,

 creating temporary illustrations with chalk and charcoal, Zinn improvises each piece on the spot and makes use of found objects, 

such as street fixtures, and stair-steps to create trompe l’oeil illusions, these are some from the last few months, but you can see plenty more on Facebook and in his 2013 book Lost and Founded, all photos courtesy the artist, what a talent, but such a pity being drawn in chalk and charcoal they will wash away when it rains.
