This street art is legal, and will likely stick around. It sits in view from Hamra street in Beirut, Lebanon. It was painted by a Chilean artist who goes by "INTI". It's obviously beautiful and carries significant meaning.
"Since the Civil War, public space in Lebanon had been occupied by inscriptions and stencils related to war and sectarian politics. Western-style graffiti appeared infrequently as of the mid-1990s. It was not until 2005 that a new scene emerged, taking on the task to create a uniquely Lebanese style of this art
form. This scene is now burgeoning and the streets of Beirut have witnessed the birth of new artists mixing caustic stencils, western influences and Arabic graffiti. These interventions contrasted with public expectations, since they promoted unity over division and maintained a humorous and often critical look at Lebanese society."-White Wall website.
This is where we see the acceptance of street art into the greater community. That can be a great thing, but we still need the street art that challenges the system, painted by people who cover their faces and run around in the dark.
