The image shows a poster with a picture of a man in a suit and tie, surrounded by text that reads "Guerra de la Retaguardia". The man in the picture is wearing a navy blue suit with a white shirt and a red tie, and he is standing in front of a bright yellow background. The text is written in a bold, black font and is centered on the poster. The poster has a vintage feel to it, with a muted color palette of blues, greens, and yellows.
