Vintage red/blue polka dots on white background, ca 1960's acetate rain scarf

Scarf is previously owned and gently worn. Good vintage condition, 1960-1970 with the wonder bread style polka dots. Fabric is likely an acetate, intended to be a rain scarf. It measures about 21" x 21" and has rolled/hemmed edging. No labels. Only one small area of discoloration (see photos).
