Vintage Bali T Shirt, Single Stitch maybe 1980s

Very cool vintage t shirt. Bali, Indonesia. Graphic of masks and says Primitive Heart Ancient Arts Bali. 100% cotton. Would look cool tucked in paper bag waist denim shorts or knotted over high waist leggings/ bike shorts. Single stitching around hem and arm. Maybe from 1980s or 1990s but I am no t shirt expert. In great condition. Tag says XL but it looks more like a Medium. Pls read measurements. •Shoulder to shoulder: 19.5” •Pit to pit:18” Length in back collar to hem: 24”
