More on Anne Orr - I haven't seen many, but all of the pictures that I have seen of her cross-stitch mosaic designs such as yours were done in solid colors, so yours is typical. Your quilt does not have a lot of different colors, but some of them have more. She was first known for her needlework patterns, including counted cross-stitch, and you can see the resemblance.
Anne Orr wrote for ladies magazines and was one of the judges at the famous Sears quilt contest in 1933.
Besides the mosaic style, she is well remembered for her applique designs.
