Here's a view of some graffiti I pass everyday on my commute. This type of artwork is common in this neighborhood. Well done graffiti like this can liven up the city. Tags are just plain vandalism. I had created a tag when I was growing up in the city, but I could never bring myself to actually put it somewhere. I just had too much respect for the owners of the property and the image of the city. So it never made it out of my high school notebooks.
