The differences between graffiti and street art can be found in authorial intent, intended audience, and form. The most common form of graffiti is a tag. A tag is a graffiti artist’s signature. Tags are text based and largely indecipherable by those outside the graffiti community. The intention behind a tag is the rebellious proliferation of the artist’s signature, akin to brand name advertising. Street art is a sub-genre of graffiti. While graffiti operates within a closed community, street art is an open invitation for anyone to interact, consider, and discuss. Furthermore, street art is drawn with a pictorial focus rather than textual, and it is rebellious but not purposefully destructive as there is intent to beautify the urban environment.
