Porcelain Door Knob Vintage Glass Buttons.
I bought these from a very old estate and that was over 33 years ago. So I have been their caregiver until now. It is time for someone else to have them.
They are very old. I don't know what year they were made but they are very, very old. I would say at least 70 to 80 Years old and they could be even older. I didn't clean them up. They are the same way I got them all those years ago and they were in a really old box at the time. A little wet rag would do it.
They look like the old vintage white porcelain door knobs.
Please let me know if you have any questions.
