Help Emily. This was used to promote funding for the arts in Milwaukee Public Schools. The drawing is done by my neice, Emily, age 5 at the time. The overall poster was to be used in a guerilla campaign where the ink was soy based, the stencils were mud, the paper was made with wildflower seeds and recycled pulp, and would be adhered to porous walls with mud. When tested during a rainy day, the entire project came off the wall and over the course of the summer flowers did grow on their own.
