In December 2007 I wrote about the "Office and Factory" sign that stuck up above the roofline of the building at NW 5th and Flanders. Thanks to thrift store cowboy who snapped a photo circa 2000, we know a little more about that business.
When the building at NW 4th and Flanders (bottom photo below) was demolished, it revealed this great "POVEY BROS. GLASS CO." sign. Brothers John and David Povey started their glass firm in 1888. John died in 1917, David in 1924. The firm was sold to a Seattle company in 1929 and disappeared soon after. Stained glass was commonly called Art Glass in that era.
Old Town Lofts was constructed on the site, covering this excellent ghost sign (2008 photo).
