CBS 2’s Sandra Torres reports.

From traffic tickets to traffic signs, they make up the “Surviving the Times” exhibit at the Center on Halsted.

“There are a lot of warning signs about what’s going on, but there’s not a lot being done about it,” says Chicagoan Sam Kirk.

Kirk referring to sex trafficking among LGBT youth, an issue that inspired her creations.

“A lot of young teens or young adults end up homeless because of rejections and they don’t know what they are doing, but they need to survive, they need to live, so they’re easy prey for sex traffickers,” Kirk says.

Kirk has been working on this project for the last three years and even did research about the issue in Chicago.

“The majority of the kids who are homeless that are at risk of becoming victims, are homeless because of rejection,” Kirk says.

For that reason the artist is selling each one of these pieces, with a portion of the funds going to the Center on Halsted youth programs.
