Now, before the copyright police get all excited, let me explain.
The logo appears to be an edited version of a famous artist’s original drawing. I assure you, no copyright violation has taken place here.
In fact, this is an edited version of an original photo taken by me:
This photo was taken in an alleyway in the city of Vancouver, BC. The photo is of a graffiti artist’s rendering of said famous original drawing. As the photographer, I hold copyright to this image, but not that one.
