antique vintage Swiss silk fabric w/ French alencon lace, ivory w/ black

Beautiful antique lace bands silk fabric, deep golden ivory with bands of cotton alencon lace? This has the original paper tag with old wax seal from F Enzler-Graf, Appenzell. The fabric measures 29" wide x 3 1/2 yards.

There's one brown spot about the size of a half-dollar along the center fold of the width, in the first 1/2 yard of the length. Otherwise, the fabric and the lace look excellent.
