Provenance is from the billionaire Herman and Claudia Uihlein 
estate and mansion.
I will be listing several elaborate linens from her collection. 

 Set of six vintage MADEIRA large formal cream-colored linen napkins with
Richelieu Cutwork done in a taupe thread.
All fabrics used in Madeira embroidery are
imported from the finest sources in the world .
A memorable setting for your holiday dinner.
Size - 22" x 23"
 They are in excellent condition, appear to be unused. 
There is one minor faint storage
spot, which is barely noticeable.

Thanks for looking.
