“The Emperor Has No B—s,” as the project is called, arrives several months after the group covered stars on the Hollywood Walk of Fame with the names of African Americans who have been killed by police. In the past, the collective has also claimed responsibility for an anti-Trump “Rape” mural on the U.S.-Mexico border and a massive piece of graffiti art in California’s Mojave Desert.
