Vintage 60s Ray Ban sunglasses.  They are marked 'B & L Ray Ban USA' and 'Tampico' on the arms.  The frame is brown tortoise, and the glass lens are a dark geen gray tinit.  They measure 5 3/4" across the front, and 2 1/4" tall.  The arms measure 5 1/2" long.  In good vintage used condition with some surface scratching on the lens/frame, and one or two deeprer scratches on the edge of the frame around the left lens.  The deeper scratches on the frame aren't obvious unless you look very close, and tilt the lens under a bright light.  One arm rests higher than the other.  Overall sturdy, and wearable.
