A Table Lamp
I took the photo on a tan background and then did a gray background which I think is better.
The lamp is all original and is very sturdy. The glass seems nice and thick to me and was not re-glued like some of these lamps are done. A strong glass chimney is inside the shade and is glued into the hole in the center. There are 3 supporting limbs that support the glass shade. I see some wax under the base where someone would have set it on a table and provided the wax to keep it in place.
Measurements: 3" tall
