Sinclair Opaline single sided porcelain sign. What makes this one scarce is that its the 6ft version, which I have only seen one decent example sell in the past. Usually I only see the 4ft ones. It does have a few hits, but very good condition compared most any other 6ft ones out there.
I have more pictures available if wanted.
Asking $2900 obo. Shipping available or deliver to Its a Gas or Peotone.
