Rare Vintage Leave It To Beaver Shirt Size M / L

Hi and thanks for looking at this amazing vintage Leave it to Beaver shirt. The size tag says Large, but measurements correspond to a modern medium. It has a small hole at the back collar, some old writing on the collar and some staining in the armpit area. I've included measurements and details in the photos. Don't hesitate to reach out with any questions you may have. All my items come from a clean, non smoking home. I only ship with tracking and insurance. Unfortunately due to losses, I only ship to Canada and the United States. Thanks again and I hope you have a wonderful day! - Mallory4960
