antique pure linen pillowcases w/ whitework embroidery, huge lovely monogram G

Pair of early 20th century vintage embroidered linen pillowcases with gothic monogram in white on white... the letter G, I think?

These measure 19" wide, 31" long to the tips of the points. They're in excellent condition showing no particular wear or use, just a few small spots, barely noticeable. There's a laundry mark as shown.
