Art galleries aren’t the only places where art is showcased. The innumerable places one can run across a great piece is mind blowing. Some places where you might expect to see fine art are inside of museums and historic buildings. Other places that are not as conventional, are typically tied to street art. These pieces are scattered about on the outside of train cars, and sometimes painted on the sides of buildings. Muralist, David Walker has been fortunate enough to have his work displayed in some of these unconventional places, and all over the world.
