caption: The image shows a Polish propaganda poster from the 1930s depicting a man holding a hammer in his hand, with the text "Dr Time Lichvu" written across the top. The man is wearing a white shirt and a black hat, and has a determined expression on his face. He is standing in front of a bright yellow background, with a black and white checkered pattern in the background. The text is written in a bold, black font, and the poster has a vintage feel to it.
