The Washington Packing Corporation was a tuna canning factory and operated in the early 1960's, until botulism killed several people who ate tuna canned by this food-processing plant.
The building has been demolished in Nov 2009, and all the graffiti art that you see on these photos has been destroyed.
It was an amazing display of graffiti art, unfortunately hard to visit.
San Francisco photographer Andre Hermann aka "shutter_se7en" published a very extensive series of photos of the graffiti in this building, which the street artists are calling "Tie's Warehouse". You can see those photos here: www.flickr.com/photos/andrehermann/sets/72157606562749963/ .
