This is a vintage sales promo sheet advertising Shaughnessy Olovnit Lingerie.  It is printed on a single piece of coated cardboard measuring 8 1/2” by 11”.  It looks to be as if these would have been promotional sheets used to make sales, as the bottom has available colors, sizes, Price, Deposit and C.O.D. information.  This one is for a Lace or Tailored Princess Slip.  It is in very good condition with no pronounced wear.
