Vintage Wool Letterman Green Cardigan Sweater. It is missing one button. This sweater does not have a size listed. I have pics of the measurements. I would say it’s a mens “Large”. I’m not sure what school or what exact year it’s from. I would say the 50s and it was made here in Los Angeles, so I would guess it’s a california school. If you have any more questions, let me know. 🙂
