Wow. This is an amazing find. Hand Print fabric by Susie Zuzek who is the designer behind the Lilly Pulitzer look. No date, but she was creating these designs between 1962-1985, and I can’t find this exact design online as a reference. This piece is 54” wide and measures 3.6 yards long (130 inches)…unwashed and ready to be made into something amazing. I’ve attached part of an article about Zuzek, and there’s a book out about her, as well as a recent museum exhibit.
