Victorian? Northwood French Opalescent Optic tumbler - dot, coin or spot?

I wasn't able to find another example of this tumbler. It has the Northwood mark on the bottom, but I am not sure the pattern's actual name. It is 3 7/8" tall.



Thanks for any & all opinions or advice!!!

Having been made in the very early 20th century, before collectors started naming patterns, the company probably called it Polka Dot. That's what most if no all of them were called then.

 

Thanks Tom!!

I was hoping you would look in on this thread. I looked through your book Glass Tumblers, but didn't see this one.

 

Because of size limitations (publisher would not print all in color if more than 288 pages) I had to eliminate maybe 400 tumblers. Obviously that was one of them. I felt the catalog illustrations at the back were more important. Sorry.

 

Don't be sorry Tom. I did find several other tumblers that I have & I know the book will undoubtedly more than pay for itself many times over.
