This insulator make was used 1938-1969.

4 inches tall

No cracks.There is a chino the inner bottom rim.
There is some black dirt most likely from the attached telephone wire. I washed in soapy bleach water and used a green scotch bite sponge to clean.

The wire around it is actual telephone wire. it can be removed if you do not wish to keep it.

Oh my goodness gracious, these are fabulous! I’ve had the cobalt version of these goblets forever (I got them as a graduation present from my grandma), and I just have always treasured them. I’m now planning my sister’s wedding, and she wants green goblets for all of the guests. These particular ones are for the girls in the wedding party, so I can keep a close eye on them ;) since they’re coming home with me afterward! I just am so in love. Thank you for the thoughtful packing and the lovely note!
