Kunstrasen is a German stencil artist who derives his name from the German term for astroturf, or a surface of synthetic fibers made to look like natural grass (fake grass). In addition to a sly bit of wordplay (kunst = art), his chosen moniker is relevant to many pressing questions in the art world today, particularly those relating to issues of authenticity, mimicry, and mass production. The life of this German urban artist is kind of mystery, on purpose or not. One of the rare things we know about his identity is his real name - according to forums, it could be Phil.
