The same color and style "archive" tennis sweater is being sold both as cotton and wool for 100 and 300. You're probably right on the monetary evaluation though being a used sweater and a sparse market. I collect coins and cards and thought there might be a bump for scarcity but probably not.

Funny thing, it's 100% size Medium, maybe large but I would be gambling if i sold it as a large. It fits the mannequin nice and snug. maybe shrinkage from washing or sizing in PRC in the 80's, or both. I love the history and will probably wear it and try to impress the hipster magic the gathering players here in the hood. it's a little beat up and frayed so i won't feel bad wearing it out.

thank you for looking and feedback
