Gorgeous! It is so hard to believe these were ever actually made from such a fragile material--and are still around! These blown glass canes were known as a "glasshouse whimsies", and were end-of-day creations made from leftover glass. They were dated from the late 1800's, to the early 1900's--this cane is around 120 years old!
It is 40-1/2" long, and has a chipped end on it--which is not surprising! The handle part is a thick twisted design, and it has the twisted design continuing down it's length. Feel free to look over the photos for all of the details.
