Photographed July 31, 2016 at the Speedway Center, a strip mall on the SW corner of Speedway and Swan. It can only be seen from the alley behind the Center.
If you can interpret the writing on the mural, please leave a comment. I interpret the initials in the upper left to be STP. It may be the tag of the graffiti crew "Sworn To Paint". Or,...something else entirely.
As usual, click on the photo for a larger and sharper image
The mural was painted in June or July of 2016.
