I acquired this at an estate sale.
The handled mug is clear with "Ridgeway" on one side.
The wrap appears to be made of maybe some kind of cardboard and has a snap.
It looks like a small piece is broken off and there is warping/buckles on the back side.

I have not cleaned it since I've owned it. Was used for display purposes only.
I feel like it will be brittle from age and will not hold up well if handled, so I've left "as is" since I've owned it.
