Fantastic octagon sun glasses.Probably from the 1960’s, possibly 1970’s.They are 6″ wide from the very outside to the very outside.Each lens measures 2 3/8″ x 2 3/8″.There is 1/2″ between each lens.there are some slight scuffs on the lenses as seen in the pictures.There are no cracks in the horn rims.I have never seen these before.
