MOBILE, Ala. — Four artists responsible for a mural project in downtown Mobile have a bit more work on their plates after vandals defaced it.

The mural, painted on a series of plywood panels in front of a storefront, depicts numerous pop culture icons including Muhammad Ali, Tupac Shakur, Johnny Cash, Amy Winehouse and Kurt Cobain. reports ( ) artist DeAnthony Dulaney on Sunday noticed those subjects as well as others, from Michael Jackson to Bob Marley and Willie Nelson to Prince each had been defaced the same way — their eyebrows had been painted white.

The vandals also left some messaging relating to drugs on the faces of the people on the wall.

Dulaney, Noelle Goodson, Stallworth and Conz8000 combined their individual techniques to begin producing the work after asking the building’s owners for permission.

“What I don’t understand is: What’s the deal with whitening out the eyebrows? Is there some meaning to it?” Goodson said.

Dulaney called the other artists to tell them what happened.

“I’m just trying to take in all this disrespect,” Dulaney said. “We aren’t trippin’ too much. It’s not that we always thought someone would do that, but we kinda prepared ourselves, since it is out there in the open. There are drunk people walking up and down Dauphin street all the time.”

This isn’t the first time their work has been disturbed. The artists have fixed small alterations to their mural, presumably made by mischievous pedestrians, before.

Dulaney and Goodson agree that the job they have ahead to restore their paintings is fairly manageable.

“(The issue is) the hassle of having to go back over your work and fix everything,” Dulaney said. “We have other stuff we wanted to add, but we first have to double back (to fix the damage). We almost had the wall done and completely covered. This just puts us behind.”

The artists said they don’t plan to fix the current vandalism until Friday’s Art Walk. “We want to do it right there in front of the people,” Dulaney said.
