While its common knowledge many slaughterhouses don't make use of a piece of meat's head, the popular misconception that it's preserved for advertising is fairly widespread. Intake and grading photographs are entirely sufficient to advertise meat sold commercially, and the practice is mostly only found in local butcher shops. Industrial operations often spoil meat's former good looks with bolt guns, and in almost all cases the head is removed and disposed of. Depending on an operation's methods this could be processing with offal, castoff, and low grade meat, to outright disposal with other landfill bound waste like use sanitary garments.
