i just found a great, austria-based website, which collects stencil-graffitis from cities all around the world. everyone can upload pictures, everyone can rate and comment them. the project cooperates with linz ’09.
“Stencilboard” aims at building an online-community by collecting and discussing Stencils from all around the world.
“Stencils” are sprayed pictures in public areas, which are produced by using stencils. The site is exclusively dedicated to Stencil-Graffities, which are in general referred to as Stencils or Pochoirs.
