Extremely rare Mac OS shirt. I have never seen one of these for sale anywhere.

Please see photo #4 it has a light flaw under the graphic. It’s kind of hard to see but there is a small stain right there under the Mac OS print.

Single stitch from the 90’s printed on heavyweight Hanes beefy. It seems to fit a true to size Large but please see the photos for exact measurements to make sure 100% it will fit you.
