I felt saddened and confused to discover my favorite mural gone, but also hopeful that another one may be in the works. Street art is mysterious and impermanent like that. It can appear or disappear overnight. Murals like these are at risk of desecration, transformation, erasure. Someone's gonna piss on it, draw a mustache on it, tag it. The weather's going to make it fade. That's part of the beauty, I think. Murals have value without being precious.
