You've probably seen the word "Super" spray-painted on buildings and bridges around the city.
It's the work of David Cox. Friday, a judge sentenced him to 10 years in prison for it. For the first time since his arrest, he is speaking out.
"It is a way of expression and if you don't like it, don't look at it," says David Cox, who goes by the street name Super.
Cox is currently is at the St. Louis City Justice Center, but his work can still be seen on buildings and bridges in St. Louis.
"Everybody, every single person from jailers, to the transport to inmates, everybody tells me 'oh man I like it, I drive by it everyday. Always compliments," said Cox.
But some say there's a major graffiti problem in the area. Millions of dollars are spent painting over graffiti each year. Cox's friends, who wanted to remain anonymous, say it's a matter of opinion.
"I like to call what he was doing art. He supported art and every artist around him," one friend said.
Cox was charged with property damage and unlawfully possessing a firearm. With a judge sentencing him to 10 years behind bars, the big question is if that will send a message to other graffiti artists?
"Everybody is going to hear about it and make their own opinion on it. Some may, some may not," said another of Cox's friends.
In hindsight, Cox says he would do some things differently when it comes to what he calls his art.
"I think I would just do it in places less visible. I don't think I would have not done it, but I don't like the situation I put myself in, my family in, my business, everything," he said.
