Unissued U.S. clip on sunglasses of the same pattern as WWII but produced in 1949. The case is the only noticeable difference, with war time cases having a smoother olive green finish and these post war cases having a pressed faux leather pattern. The glasses do need a good cleaning as they've been in storage for over 70 years. These should fit standard period frames. See comparison photos to an original 1944 dated example from my collection.
