Hidden in plain sight! This is a heavily degraded, large ghost sign found on Court St. between Vine and Race Sts. in downtown Cincinnati. I can’t make out the top part, where the brand would be, but the bottom clearly says “extra six-cord.”
As far as I’ve been able to research, extra six cord spool cotton was a type of sewing thread manufactured by several companies including Willimatic and Kerr & Co. Was this a sign for one of those brands?
