Tracy Lee Stum's Incredible 3D Sidewalk Chalk Art

I've uploaded more 3D chalk artwork and thought I'd create my own 3D effect of them on this blog. One can see how the 3D photos are placed under the menu at right that has a slight shadow making them look multi-dimensional.  The following 3D artwork is by a preeminent artist Tracy Lee Stum who holds the Guiness Book of World Records title for largest 3D chalk painting in the world.

"A professional street painter or madonnara, Tracy Lee Stum is a fine artist committed to creating spectacular modern masterpieces that transform, captivate and inspire.”She is best known for her 3D street paintings, also called anamorphic or pavement chalk art. “3D Anamorphic Street Paintings are illusionary 2-dimensional images that appear to become 3-dimensional when viewed from a fixed point through a camera lens.” “Tracy has been creating these types of chalk art images since she first started street painting and continues to challenge herself through this manner of visual expression.” –3D Stree Paintings of Tracy Lee Stum - VillageofJoy.com

I guess my question is, after all that effort and work do they simply allow these works to fade and wash off in the rain?  Or do they spray it with a sealant. It would be a real waste for this artwork to be lost, it's that good.
