The Limited vintage lambswool cardigan

Vintage, bottle-green cardigan sweater with a rounded neckline in a midnight blue trim. This same midnight blue trim also accents the long sleevesat the wrist. The cardigan does up with metal button accents, of which there is one missing just above the waist . Signs of wear are noted at the wrist of the sleeves; pls see pictures. Sadly, a label with the exact yarn type is also missing, however the fabric feels like it's either a 100% wool or a mainly wool blend. The sweater is lightweight and stretchy. Size label is missing but I judge it to fit a small. Care instructions are also missing however the likely wool yarn would require hand washing or machine wash in delicates and cold water.
