After gaining fame as a notorious worldwide graffiti writer, PETRO stunned the graffiti world with his unique, nostalgic and naïve early-eighties mentality. He then took this approach to the art world. His unhealthy obsessions for all things peculiar, involving childhood drawings, graffiti, Ralph Lauren, the lost and found, pattern repetition and biscuits, have become a major part of his work. His back-to-the-basics method can be seen as a reaction to fundamental questions in the art world like what still counts as art?
As a homeless nomad PETROs shows are usually overwhelmed with references to the country or city in which he exhibits at the moment. His work is often a direct response to his ever-changing surroundings: where he is, he creates. This makes every show a unique happening. Staying true to his particular art-ethos each show he does functions as a fund for the next one every time in a different country.
