Kwakzalver 1847 - 1889

"Kwakzalver" (Quack) is a black and white etching by German artist William Unger, depicting a street scene with a quack doctor surrounded by townspeople, perhaps attempting to sell them a cure-all tonic. Unger's detailed etching style is evident in the intricate lines and textures that capture the figures and their surroundings, creating a sense of realism and depth. The artwork, dating from 1847-1889, is currently housed in the Rijksmuseum in Amsterdam.
