VTG Maverick 60s 70s Western cowboy shirt piping - size m snaps blue made in USA

Very light blue with a unique red, white and black plaid shoulder detail. Maverick was a sub-brand of Wrangler like Rustler is now. Kodel is a polyester fabric used in the 60s and 70s. The snaps are black. Shirt could fit a slim medium, fits almost perfect on a 140lbs 5’11” male. See last pic. Some minor stains on one sleeve and the collar, could be easily resolved away but I don’t notice them much. Very lightweight and breathable for summer even tucked in! 22” chest 17” shoulders 15.5” neck 33” length 26” sleeves
