Absolutely mint condition, never been used, in the original box with a tag stating "Rouge Koral Power Naturelle". The vanity's power and rouge still have the pressed marking "KARESS WOODWORTH' and never been used puffs and embossed tissue paper.
The case is Silver Plate with a niello accented, repousse floral and tendril design on the lid, bottom and inside. The rouge compartment is stamped "KARESS WOODWORTH NEW YORK PARIS" and the patent number 1570382.
Woodworth was known for transforming the vanity/compact box from a simple container into accessories that were both functional and attractive.
This book piece is pictured on page 18 of Collectors Encyclopedia of Compacts Carryalls and Face Power Boxes by Laura M Mueller and page 19 of the same book has an advertisement showing the double vanity in the box.
The vanity measures 2" x 1 5/8" x 3/8" and the outside box measures 3" x2 1/2".
I have not tried to clean this vanity, it has its original patina.
