_Ach armes Kind! er ist kaum zu erkennen!_ Maximiliane von Blittersdorf geb. Brentano und ihr Sohn Ludwig, krank an den Röteln (als Forelle) 

This pencil sketch, titled _Ach armes Kind! er ist kaum zu erkennen!_ Maximiliane von Blittersdorf geb. Brentano und ihr Sohn Ludwig, krank an den Röteln (als Forelle), by Moritz von Schwind, humorously depicts a young boy in bed, his head transformed into a trout. The humorous use of the fish head, referencing the German word for measles "Röteln," which sounds similar to "Forelle" (trout), is characteristic of Schwind's whimsical style. The sketch, now at the Städel Museum, exemplifies the artist's talent for combining playful symbolism with heartfelt observation.
