A menacing Donald Trump is gazing down on Phoenix's Grand Avenue.
The president is flanked by mushroom clouds and swastikas looking like dollar signs.
"I think a lot of people are feeling this way and I'm just trying to express what I think is on a lot of people's minds these days," the billboard's artist, Karen Fiorito, said Friday in an interview from her California home.
"Something that really concerned us was this idea of a dictatorship where things were going in a certain direction."
The billboard was commissioned by the owner Beatrice Moore, a longtime patron of the arts on Grand Avenue.
"Some of these issues are so important you can't not speak out," Moore said in an interview.
The Trump billboard went up Friday to coincide with the start of the annual three-day Art Detour event in downtown Phoenix. Moore said it would remain up as long as Trump is president.
Moore and Fiorito do expect blowback from Trump supporters.
"I just hope that everyone involved in helping bring this message out is safe and that we all get through this unharmed," Fiorito said.
