1914 French Hand-knotted Lace Sample Mounted with Pattern

Boldly graphic and very finely detailed at once, this is a 1914 hand-knotted lace sample, with pattern, hand-drawn on orange card and used in the process of making the lace (pin pricks everywhere) mounted below. I presume done by a young woman mastering the art of making lace, though sometimes one sees similar things done by teachers, or professional lace makers, as examples. With what looks to me a signature on the pattern. All mounted to blue card-- the perfect complement to the orange (with pattern drawn in red and black ink) and white (cotton I believe) of the lace. 

 10 5/8" x 6 7/8" and in very good antique condition.
