When writing home, be careful not to reveal military secrets! 1954

Created by K. Ivanov in 1954, this Soviet poster “In the letter home, watch out, accidentally do not blab out a military secret!” warns soldiers to be cautious when writing personal letters. The image shows a smiling soldier composing a message to his family, while in the next scene his mother reads it aloud at the post office, unaware that others might overhear. This everyday situation illustrates how even innocent words can reveal confidential information. The bright and friendly colors contrast with the serious warning, reminding everyone that carelessness could harm the country. The poster reflects the Cold War atmosphere of vigilance and responsibility in protecting state and military secrets.
