unused vintage silver damask table linens w/ labels, tablecloth & dinner napkins

Beautiful silky rayon damask table linens set, mid-century vintage, made in Japan? We love the unusual silvery grey color! The tablecloth measures 56" x 74", and the eight dinner napkins measure 16" square.

The napkins were never used or laundered, and are crisp and glossy. The tablecloth has been used, and shows a few light marks, which we haven't tried to remove.
