You are right about the date. It was made from feed sacks that feed was put in during the 1930's and 40's. A lot of quilts and clothes were made from those sacks. I have several of the ones that are in your quilt. It is certainly a nice vintage quilt. Handle with care. You can machine wash if you place it inside a super large cloth bag like a big pillow case. That way, you can let it soak awhile. I use Shout on any stains and then let it sit in some oxiclean for a while before washing.
