exhibition paper stencil

We supported an art exhibition project from a university at our hometown. We designed the exhibition catalogue (which will be printed during the next weeks), the wall prints and this exhibition papers you get for free. The exhibition shows contemporary art and we had the idea to make stencils so that the visitors can do there own art outside or at home with this cut out "Stadt in Bewegung" which means "city in movement". What do think about the idea?
