caption: The image shows a poster advertising a swan wearing a pair of ice skates, with the text "Dr. Gensner's Olmwahl's Lederpohl" written above it. The swan is depicted in a graceful pose, with its wings spread wide and its head slightly tilted, as if it is about to take flight. The text is written in a bold font, with a bright yellow background, giving the poster a cheerful and inviting feel.
