vintage lace edged sheer cotton baby pillow cover for boudoir bolster

Vintage sheer fine cotton pillowcase for a small cylindrical pillow, like a little colored satin bolster, boudoir style! It's in excellent condition, I don't believe it was ever used.

The cover is edged in delicate lace, and open at both ends. It measures 10" wide, 17" long not including the lace edging.
