The Artist/Creator of the mosaic mural is, Mauricio Robalino. You can see more of his work (including this particular mural) HERE: The Walla Walla Mural is the 2nd one down on the page. It has a Full Length picture of the mural (straight on) which I could not take because there just wasn't room. Instead I have a side view that I took with my Wide-Angle lens on the camera.

This mural measures 44 feet by 6 feet.
