Pendleton true vintage rich red green black plaid wool board shirt L/modern M

Really beautiful vintage wool Pendleton board shirt with a glowing true red plaid. The colors are richer and more vibrant than they appear on my monitor and the wool is drapey without being too thin or thick. One super-cool special thing: the buttons on the cuffs are green and ones on the torso are red. No condition issues I could find; marked L but suits a size M or maybe even a small depending on if it’s worn by a man or woman.
