The image is a vintage propaganda poster from the American Library Association. It features a soldier kneeling on top of a pile of books, with a rifle resting on the ground next to him. The soldier is wearing a helmet and a trench coat, and is holding a book in his hand. The background shows a city skyline with buildings and a body of water. The text on the poster reads "Knowledge Wins" and "Public Library Books are Free." The poster is promoting the idea that knowledge wins and that public library books are free.
