60s vintage Dolly Madison all cotton comforter or duvet cover, moody green wide stripes on white

Still sealed vintage 100% cotton comforter cover, cute Dolly Madison package. Package is marked 'sized to fit a 72" x 84" comforter' (a full, or maybe a queen size?). I love the colors here - moody green in crisp white. Package and contents look very good, clean and bright.
