1930s vintage glass beaded embroidery, hand embroidered flower basket cotton muslin pillow cover

Vintage hand beaded embroidered cotton pillow cover (no pillow), about 13" x 14", knife edge shape with the same unbleached ivory cotton muslin front and back. The seed beads are all glass. I can't begin to imagine a project like this - embroidery AND beading, with all the tiny beads carefully secured in place. Simply amazing. It's in very good condition, no spots or discoloration.
