Vintage [American Optical] glasses from the late 1930s to the early 1940s. The worlds oldest eyeglass maker, commonly known as AO, is a historic brand that laid the foundation for eyeglasses. A full-view type round frame with a temple developed in the car society at the top, engraving by a watchmaker at the time of the war. Is a delicate and elegant design. Bread with a slightly flat upper part and a valuable type with a slight style. The actual size of the temple is long for this type, so it is easy to put on. It is a 12Kt-Yellow Gold gold-plated specification. We have newly added a grayish green color UV lens. It has been maintained at the eyeglass store. The size of the wire (nawate) can be adjusted. (At your local optician) We have scrutinized the condition, but since it is a vintage item, there are threads and scratches. Please purchase after understanding the characteristics of vintage and antique.
