Vintage Glass Tree Topper European Yellow Mica 11"

Vintage Glass Tree Topper with original box. There are no markings to indicate where it was manufactured but attributed to Europe, similar to those produced in West Germany or Poland. This Topper is approximately 10.5 inches tall, and the bulb is about 2 inches at its widest. Has white mica accents in a leaf liike pattern. Some wear and discoloration are consistent with age but no chips or cracks. There is some residue as shown in photos on the inside. I'm not sure what that is, maybe tree sap? See photos.
