Vintage 1970’s Pendleton 100% Virgin Wool windowpane plaid button down shirt

Vintage 1970’s Pendelton Virgin Wool button down windowpane plaid patterned shirt. In shades of heathered blue & tan, this shirt is in fairly good condition considering its age. Button is missing on left cuff (I suggest moving the one at the collar) & there is a small hole on the back- see last photo. Men’s size medium.
