Car ashtray in vaseline glass green/yellow cream slag that glows under blacklight. These have been commonly mistaken for insulators because they DO look like a small threadless insulator! They were held to the dash of cars in the 1920's-30's with a suction cup and come in some amazing color combinations. I have had several of these pass my way and all have sold for over $125-$140.V NM condition, it does have a crack (NGM)at the hole where the suction cup was attached and you're looking directly at it. Displays great. To your doorstep in USA/CANADA for $70.Other countries I'll assist with shipping.
