Vintage space dye boucle sweater, size S

Truly wonderful 1970s(?) bouclé sweater. Has V-neck and slightly exaggerated cuffs. No tags to indicate size or fabric content but fits like a modern women's S, 17.5" pit to pit. Feels like acrylic? But is not pilled at all, so...cotton? I don't know. Unique taupe, navy, aqua and violet space dye. Looks perfect at a glance but has a few small pulls and a tiny bald spot in front, please see last photo. She's still a beauty.
