Satan's Laundromat is a really cool photo log, posting pictures mostly of urban areas, and interesting signs, mostly in New York City. This post
features signs in San Jose, most of which I'm well acquainted with. Erick and I have always gotten a kick out of "Mr T's Liquor Locker".
I don't know where the name Satan's Laundromat came from, maybe he says something about it on the site. I haven't checked.
Update: .This site
also has some classic San Jose signage.
