It certainly has a Showa retro design and color. A mint green knit cardigan. Features a contrasting color collar and buttons. Elegant mint green with beige lines. Has pockets. Likely from the 1980s. Authentic vintage. No signs of wear. It's in such good condition, possibly even new, due to excellent storage. Non-smoker, no pets. No strange odors. I found it while cleaning out my parents' house.
