Vintage oversized Tiffany M. Mindy beige/brown eyeglass frames.   Clear to brown gradient. Size 50-18-135.  New old stock from a retired optometrist's display found at a vintage/antique auction. Ready for your prescription lenses. 

NOTE:  All of my vintage eyeglass frames were purchased at a vintage/antique auction.  Although they were never worn, due to handling there may be light scratches and/or need adjustments.  All of the ones with glass are non-prescription.

ALSO NOTE:  The model’s head measures 21” around (just above the ears).  The frames may be bigger/smaller than how they appear in the picture.   I have included the “Eye Size-Bridge Width-Temple Length” in my description (i.e. 56-16-140).  The measurements will be in “mm”.  These are the numbers you should use when determining the size of the frame.
