The Nite Owls (or Nite Owl) Club was an illegal operation in Pittsburgh, PA, around 1938. (I have a couple of chips that came with them showing just Nite ‘Owl’ in a different design but not for sale) Extract from local newspaper in 1938 is below.
I have a few each of the 6 chips shown above available. 5 of the designs are same both sides.
Single chips from the top row are available for $10 shipped each.
Single chips from the bottom row are $7 shipped each.
Set of 6 is $45 shipped.
Email me if interested.
