This is a graphic design poster with a strong visual impact in a retro style. The image uses a classic yellow and dark brown color scheme, creating a warning or industrial atmosphere. The composition features a stylized black fox head silhouette on the left with sharp lines and a piercing gaze, while a skull with crossbones on the right symbolizes danger. The background is decorated with jagged lightning or mountain shapes on both sides, enhancing the tension. At the bottom, prominent text reads "ČERNÉ LIŠKY" (Czech for "Black Foxes") in black, and "NEOLIZUJTE" (Czech for "Do not Neolithize") in large red letters. This absurd combination of text and image gives the work a unique surrealist humor and satirical meaning. The overall design is concise and powerful, featuring a strong Pop Art and Brutalist style.
