These cool vintage Gucci eyeglass frames are circa 1970s. They are made from lucite and look as if they are tortoise shell. They have the double G on each side piece in gold. The front measures 5 3/4 inches wide, from side piece to side piece and the lenses are just under 2 1/4 inches from top to bottom. The side pieces are 5 1/4 inches long from the lense to the ear tip. I have a medium size head and really short hair and they fit me but feel a little loose on my head. They are in good condition with the exception of chew marks on the ends of the ears pieces. Don't know if these can be polished out or not. They are marked Gucci and have some numbers listed that are worn but may be 58 23 708, which may or may not tell you the size?
