Cream/Off White Vintage 1950s Gender Neutral Unisex Award Sweater

This was my Grandma's when she was in high school. She graduated at some point in the '50's. This is an official award sweater by vintage label East Tenn or east-tenn and is made out of an actually decently comfortable acrylic. I don't believe there are any stains or wear or holes from what I saw. The buttons are a beautiful shiny plastic that I assume i going to be Lucite or possibly also acrylic, but I know for certain it is not Bakelite. It doesn't have a size attatched but I do assume it's likely a small or maybe a medium in womens and an xs in mens.
