There used to be a building here. It was striped, white and black. A fairly anonymous building where people used to work. I drove by it any number of times; now it’s gone. No doubt something will replace it soon enough. Which means the drawings and tags on the retaining walls are definitely temporary. A couple of them are interesting, notably the horse and bird and the Statue of Liberty.
Located at what would have been 2101 West Linden Avenue, on the west side of 21st Avenue South. You can park on Linden easily and walk down into the ruins. This is likely to be a construction site before long, however.
