This one's a conversation piece as much as a work shirt. A khaki Columbia button-down (XL, made in Sri Lanka) carrying an embroidered chest patch for "Swordfish / Neptune Spar / Ivan / Nile" over an illustrated oil platform - tied to a real Gulf of Mexico deepwater project where the Swordfish subsea field ties back to Kerr-McGee's Neptune Spar. Great grab for offshore/oilfield collectors, workwear guys, or anyone into rare corporate patch pieces. Button-down collar, chest pocket with Columbia branding, cuff patch on one sleeve. Good pre-owned condition, shows honest wear consistent with use, no rips or stains noted.
