These Silhouette eyeglasses are model 500 and deadstock; they still have the original sticker that lists the model and size (covering the “Silhouette” stamp). I’ve seen these listed as being from 1978. The frames are tortoise shell with silver plastic cut-outs. They are size 54/16, with a 140 temple size. They were made in Austria. The sample lenses that are currently in have scratches, and there is also some very minor surface scratches on the silver. Otherwise, they are in very good condition.
