This is an antique pair of glasses found while cleaning out my parents' house. The glasses themselves are small. The lenses have small scratches and scuffs. The lower part of the lenses have a different prescription. The glasses case is marked with "KAHEI NAKAMURA." The case is quite damaged. These glasses were in this case, but I don't know if the glasses themselves are a KAHEI NAKAMURA product, so please be aware of that. As you can see in the third photo, when magnified, it says "1/10 12KGF" and there is fine engraving as shown in photos 4 and 5. The address of the shop at the time is written in the sixth photo, but it seems to be a very old address. After researching, it appears to be glasses from "Nakamura Megane-ten," a high-end glasses shop that was once located in Nihonbashi Ningyocho. This glasses shop, founded in the Meiji era, reportedly spent 20,000 yen on a signboard made of solid cypress, with the characters written by a first-class calligrapher and carved into a marble plate, covered in gold leaf, in an era when a house could be built for 2,000 yen.
