I graduated from high school in the mid 50s and our colors were more subdued and smaller prints. This reminds me of the 1960s when anything went as far as color combinations. I saw a quilt book from the 1960s and the colors and prints were very similar. I have a feeling that since it was machine pieced the maker intended to machine quilt also. Women were proud of their ability to quilt on their sewing machines. Decorative stitches were still a novelty on their sewing machines.
