Vintage Crazy Quilt 86" x 69 Heavily Embroidered Pastel Colors Old Hand Tied

Vintage Crazy Quilt 86" x 69 Heavily Embroidered Pastel Colors Old Hand Tied It has several areas of staining on back and some staining on one of the orange fabrics on the top. I did not notice any other staining on the top but it is possible I missed something in the busy design. This is a lightweight quilt, it weighs 3lb 12oz. It is very elaborately embroidered with many colors of thread. I don't know the age but I am guessing the fabrics are 40s/50s. Some of the fabrics are embroidered and some are shiny, possibly rayon or acetate. Others of the fabrics seem like cotton. Please see all photos for condition. B19
