I've owned this insulator for a few years, but it's never made a public appearance until now. There is an impression of a Bambi-like deer on the dome top with the words "Spotted Fawn" below. This was evidently a child's charm of some sort that was tossed in the mold. The charm likely adhered to the glass and remained there for some time until it weathered away while in use. You can still see the remnants of what appears to be brass residue. It was found on Martha's Vineyard Island, MA.
