This handkerchief is almost exactly 14 1/2" square. It is made of cotton batiste and Bedfordshire lace.

The lace constitutes an edging AND and border inserted into the batiste, sort of an entredeux.

There is a "C" monogram, it is appliqued, and I wonder if it's a bobbin lace applique.

CONDITION OF HANKIE: Two places where the the cotton batiste pulled away from the lace, shown with pencil erasers pointing to them. 
A small hole near the border, also shown with a pencil eraser pointing to it.
 And finally, reddish mark on the batiste, again, a pencil eraser is pointing to it, last photo.
 Hand laundered, lightly starched and pressed.
