I was walking through my favorite alleys of Vancouver looking for any new graffiti art and I actually found 3 graffiti artists hard at work on a private parking lot. The owners were tired of all the tagging along their walls and decided to allow proper graffiti writers to refresh their walls with a proper mural from time to time. Even the taggers stay off a properly done up wall out of respect...for a while anyway.
I ran into Combo (professional tag name), Joe and Jordan "The Red" working on this Simpson's themed graffiti mural wall at 300 block West Hastings. They were hard at work trying to finish their cartoon masterpiece before it started raining.
These guys work hard and they work fast, and they don't get paid for what they do... at least not these guys. They can spend up to $100 worth of paint for just a 20' x 15' section, and this mural was probably over 120' x 15'. Why do it then? They're artists. Why did Picasso paint? To become rich? Many artists die poor. They do it because they want to express themselves.
