Product code: Vintage eye top glasses
Antique H.J. Belson M.D. Eye, Ear, Nose and Throught Manitowoc, Wisconson Eye glasses Unsure of brand and age but in great condition due to age Has original cleaning cloth included  on that cloth it has a phone number with only 4 digits  Around 1920 to 1930 is when they switched to five digits  so I'm guessing the top glasses to be around 1910 range. Please do your own research. This is just what I read on the Internet. .
