Airwolf Graphic T-shirts

Airwolf was a supersonic and armed helicopter that could blend in by appearing to be civilian and non-military in origin — "a wolf in sheep's clothing." Airwolf's insignia patch, as designed by artist Andrew Probert and, as worn by the flight crew members, was a snarling wolf's head with bat wings that appeared to be wearing a sheepskin, complete with the head of the lamb over the wolf's forehead; a direct play on the saying. -- Wikipedia
