|Plastic tumblers from Etsy are unmarked and probably resemble Laureline, these available at the DaileyShopper|
I had a reader write in to me about a drinking glass he had growing up with the inscription, "Laureline.". I had never seen that before per se on a plastic cup, but I did a little research and found this was a Belle Kogan design introduced by Boonton in 1956. This came from the book, "China and Glass in America." The earliest reference to the word Laureline being used in the plastic industry was 1952 in a Hardware Age magazine, but I'm uncertain if this is the same type plastic used in the tumblers.
|BooksShop on Etsy has this 61 pc TexasWare set for sale, note the blue plastic "AKA GLASTIC" drinking vessels up top on either side of the top shelf, this is probably what Laureline looked like!|
These "plastic drinking vessels" were very similar to the plastic glasses that were crystallized by TexasWare. Not sure if you remember them from your younger days eating at the Ponderosa or buffet style restaurants, but they were plastic frosted type glasses that I thought were cheesy. I used to call them GLASTIC, a mix of plastic supposed to look like glass. They often had stress cracks in them and / or chips on the rim. Ewwww.
If you know anything about Laureline, let me know.
