Let me say right up front that I don't know anything about this paperweight other than we've had it for over 30 years.
It is about 2 inches tall and 2-1/2 inches across.
No maker's marks.
Clear glass with red, yellow and blue swirling through it. Looks like there are tiny bubbles in the blue.
Excellent condition, small wear line on side. No cracks or chips.
That's a reflection of my window that you see in the photos.
