The reverse panel of a hand-crafted wooden novelty gift bears a comic caricature captioned 'Keep Your Mouth Shut,' a playful nod to the wartime culture of secrecy embodied in slogans like 'loose lips sink ships.' Items such as this small folding wood booklet were often made or purchased by cadets as humorous keepsakes for instructors, blending affection with the irreverent humor common in military training camps during World War II.
