A little more info on them …… via correspondence dated 1987 from the Fostoria Glass Society, Moundsville, WV, they confirmed it was made by Fostoria and production ranged from the mid 60’s to the mid 70’s. They were only made for and sold by Cy Wright and the colors were Ruby, Green and Amber.
So, there is more of them out there somewhere ..... but those 2 Ruby ones are the only 2 we have ever seen.
