For sale is a vintage 90s Machine Head shirt, not sure if this was made by a fan or a real licensed piece. The patched is licensed to Blue Grape and dated 1996 I believe. The shirt itself is in good condition with no major issues that I can find. Fits pretty big, XL seems accurate. See below for measurements.
