http://www.photog.com/gdead/70s/Dillon/dillon8.html fits the bill quite
nicely (except it's also got a copyright on top of it.)
Other WOS photos are at http://www.photog.com/gdead/70s/dillon.html

Sorry for the off-topic question, but I thought I saw a
post here some time ago that referenced a web site someone
had with lots of pictures on it. I searched my saved
messages but couldn't find it.
Specifically, my brother is looking for the picture of
Garcia with the Wall of Sound behind him.
