The Collision Auto Works sign was in pretty bad shape in 1996 when the first photo was taken. By 1998 it had suffered some pretty serious tagging damage. Stand on the corner of NW 12th and Everett and you can see what's left; the graffiti is covered over so the original ad is just about gone from view.
I don't expect the West Bearing & Parts shop to be there much longer. It's empty and property values are just too high for a worn out old one story building.
