This poster aims to recruit men to join the army during World War I. It depicts a man looking sadly through a window, with the army side portrayed as light and positive while the outside is dark. It uses emotions like guilt and alienation to suggest that men who don't enlist are merely spectators and not truly helping their country. The message aims to inspire patriotism and convince men they can make a difference by enlisting rather than remaining outside as spectators. It lacks facts and exaggerates emotions to manipulate viewers into joining the army through a sense of duty and belonging.
