Forget the Liberty Bell. There are more colorful sights in Philadelphia.
For 30 years, the Philadelphia Mural Arts Program has brought collaborative creativity to the City of Brotherly Love by way of 4,000 large-scale paintings scattered throughout the city.
Jane Golden, founder and executive director of the program, joined CNBC's "Squawk Box" to share her inspiration. "People are coming here from all over the world to see the incredible work. There's a real renaissance happening in Philadelphia that I could have never imagined."
The interest and passion over three decades for this transformative art have translated into exponential growth for Mural Arts, and Golden said hundreds of cities in the United States and around the world have spoken with her about replicating the project.
