It is impressed with the FENTON logo on the back side near the bottom. 

Difficult to read number below impressed “Fenton” logo, but appears to be “8”, meaning it was made in 1980’s. (Regardless, my belief is that it is from the late 20th century.)

Measures about 3" tall by about 2 1/2" wide.

Heavy, it weighs about 11 1/2 oz.

This satinized and opalescent version of this Fenton owl is very rare to find.

Glows beautifully under a black light.

I always pack glassware carefully before shipping, and THIS ITEM WILL BE WRAPPED AND DOUBLE BOXED.

Thank you for looking.
