This is a landscape image of the Great Seattle Graffiti Wall stitched together from about 20 individual photos. This wall can be seen along the 3rd St. Amtrak train approach in Seattle's SoDo district, on the backside of a warehouse right across 1st St. from Starbuck's world HQ.
As I was taking the photos for this shot a woman came out of the building and told me, "I should charge admission!" She apparently allows young artists to ply their skill along the back of her warehouse, a great treat for Amtrak and Sounder commuters with nothing but grey to look at.
