This black t-shirt features a bold graphic design that humorously warns against questioning the expertise of coal miners. The central image depicts a skull wearing a miner's helmet, crossed by a pickaxe and shovel. The words "TELL THESE COAL MINERS HOW TO DO THEIR JOB AND YOU CAN TELL THE DOCTOR THE LAST THING" printed above and below the graphic add a touch of dark humor. This tee would make a cool and funny gift for coal miners with a sense of humor.
