Powell's Books, 1918
The repair work at Powell's City of Books just keeps unwrapping more gifts. Following the uncovering of old structural beams from the building's days as an auto dealership, posted here and here, this newest discovery reveals two layers. "ALL REPAIRS & PARTS" and "ALL LABOR & MATERIALS" share the top line; I can't tell which was painted first. "STRICTLY CASH" is on the bottom line.
