Identify these sunglasses
Hello All, I found these sunglasses in an old shotgun shell ammo box with an embroidered handkerchief with the British Flag, the American flag and Lady Liberty that says "A souvenir from the World War" I cannot find any information about these anywhere, any help is appreciated. They have one mark on the right ear stem hinge which is two vertical lines then a square standing on its corner (like a diamond but definitely square shaped) then followed by two more vertical lines.
