Young's Marble Works, 1880
This ghost sign is barely visible now. It appears to have been painted over at one time, has suffered some graffiti damage, and has weathered significantly over the years. It is passed thousands of times per day by people crossing the Burnside Bridge yet you have to look closely to see it; it's tucked away from the street and overlooks a demolished building's garbage-strewn basement. It's on the south side of West Burnside between 1st and 2nd. Next time you are at Saturday Market, walk up to the bridge sidewalk and take a look.
In addition to the marble works, the two-story brick building has been used as a factory, warehouse, retail establishment, and is currently home to the Salvation Army.
