this art work depicting mushrooms on the Bansky art wall at Erie and Mission street no longer exists. Apparently somebody with the building owner complained from the public complained TO the building owner about the mushrooms on the wall and they painted over it. So this may be the only existing photo of the mushroom art work
It was only up for one day last week. This is what it looks like now
Kind of like watching R rated movies growing up as a kid, huh?
