Expo 86 Official Volunteer T-Shirt (XL)

Anybody remember Expo 86? I sure do, because my mom was a volunteer there (which is why my brother and I got to go several times). Official T shirt my dear mother wore for her shifts at the British Columbia Pavilion of Expo 86 in Vancouver. No tears or stains. Approx 23 inches pit to pit, 25 inches long in the front and about 4 inches longer than the back (see photo - love those 80s ways!)
