That Windblown Tulip is my favorite...I remember working on one of those as a Raffle Quilt with our guild in Nebraska. We used all pastels...yellow, blue, pink, rose and lavender for the tulips. It was a very popular pattern. From the looks of the green in your quilt, I would say it might be from the 30's. It has that look about it. It's a beautiful quilt for sure...you have a real treasure there.
