Umbrella Girl, NOLA

Here we see one of Banksy's most beloved street pieces, painted on a wall in New Orleans in 2008. A young girl stands in her dark dress, holding an umbrella above her head. But there's a twist that makes you look twice. The rain isn't falling from the sky. It's pouring down from inside the umbrella itself, the very thing meant to keep her dry. She reaches out one hand, as if checking whether the strange weather is real.

Banksy created this work three years after Hurricane Katrina devastated the city, and the timing was no accident. Many people read the image as a quiet comment on how the protection we count on can sometimes be the source of our trouble, whether that's the government, the levees, or simply false promises of safety. Like much of Banksy's art, it was made with stencils and spray paint, a quick method that suits the secretive nature of street work. The black and white figure against a plain wall is simple, but the idea behind it sticks with you long after you walk away.
