Cabot's quilt notes state the following:
"The why and wherefore of the title of this quilt, YOKOHAMA BANNER are unknown, but there is one definite fact, and that is that it is one of the most interesting and individual pieced blocks seen for some time. Fundamentally, the pattern is a four patch design, but consider the center patch and there is a windmill. In each of the four patches are four smaller patches. Looking at it from another angle one sees a series of flying flags. The quilt is set together with pieced blocks, and bound with a half inch bias binding."
