Nice old cotton ticking pillow cover - this is just a case, meant to be filled with goose down or chicken feathers (or whatever you'd like for fill).
I've shown it over a pillow in one photo so you can see it properly, but the pillow is not included. This pillowcase measures about 19" x 25" overall, fits a standard size pillow fine.
It's an authentic vintage piece right out of a farm estate here in Wisconsin. That's a real patch, hand sewn, not just some decorative thing! It's in good clean condition overall, slight browning, fairly even in color.
