Vintage Lariat leathers Jacket

This Jacket appears to be brand new. my great aunt had it in her closet when we inherited the home over 10 years ago. According to older family members she had it made sometime in the 70s or 80s, although no one knows for sure how old it really is. Like many things she owned, she likely wore it only once or twice. It is a size 16 and USA made. The buttons say RAU Co. on the back, and on the inside behind the fabric there are marks from the original makers. (see pic) The original price is unknown but similar online jackets are listed and have sold between 150 and 400.
