Never used vintage blankets in blue and white - these do have some spots and soil marks from storage which will probably come out with washing.
The Cannon label blanket is 100% polyester with nylon binding, size is 72" x 90". It's the Wedding Ring quilt print in blue and white.
The solid blue blanket is about the same size, goes beautifully with the printed blanket. It's a Wards label, I think?, all acrylic, soft and not at all scratchy.
