vintage hand blown smoke glass tumblers, twilight grey seeded bubbles drinking glasses

Vintage grey smoke glass drinking glasses, nice and big. These are almost 6" tall and hold 20 or 22 ounces. They're hand blown, so no two of them are absolutely identical.

These are not marked or signed that I could find, and I'm not sure where they were made. Mexico? Recycled glass from Spain? Fire and Light? Everyone here seems to have had a different idea.

And all I can say for sure is that they are lovely and heavy with bubbles, a beautiful smoky grey color, and that the whole lot of five of them are in excellent condition. Enjoy!
