Three vintage wool sweaters, found at an estate sale.

Three vintage sweaters, found at an estate sale. First one made by rugged American size medium 90% wool. Second sweater, environmental clothing made in the USA size large and third one. The tag has been taken off but I believe it to be a medium. Please see pictures for condition. The American has small discoloration on front, which is pointed out in picture. I have not tried to clean or get the stains out.
