Custom Tee rare

Grey Tee shirt; size XL, Brand GILDAN; Custom tee honoring victims of "Wounded Knee". Purchased at the Pine Ridge Reservation Trading Post (Singing Horse Trading Post) about 2015. May not be true vintage but its vintage to me. Its been loved and worn only once. It has deep meaning to me, hope someone else will love it also. This item was bought new by me. https://www.singinghorse.net/
