Vintage worsted wool twill turquoise, teal green Pendleton western slant pocket inverted pleat back shirt with glass buttons. Wide chest medium or large size. Only missing one button at the very bottom that would be tucked in if you were wearing it like that and a couple of the ones on the cuffs are chipped, but in decent condition.
Some small holes on the back and a tiny one near the wrist, all are certainly fixable. This is an older old label for sure as I have a jacket from the 40s or 50s which has a similar yellow instead of blue label.
