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

Beautiful crisp and silky rayon damask table linens set, mid-century vintage, labels marked Czechoslovakia. This set was never used or laundered, it's still tied up in the satin ribbons. The tablecloth measures 68" x 106", and the twelve dinner napkins 20" square.

This set would be perfect, except there are yellowed marks left from labels stuck on with cellophane tape. We don't how how best to remove the marks, and have not attempted to clean these at all.
