Vintage LL Bean Navy Wool Cardigan Sweater Small

Vintage LL Bean Wool button sweater. Very heavy and warm knit. Dark navy blue (possibly off black?) with silver metal buttons embossed with a crest. I think one button may be missing on the top of the collar but if you don't wear the collar popped you won't notice it. Two nice deep front pockets. Size Small. No holes or snags. It seems to have a nautical style to me.
