Les Demoiselles d'Avignon

Les Demoiselles d'Avignon (The Young Ladies of Avignon, and originally titled The Brothel of Avignon)^[2] is a large oil painting created in 1907 by the Spanish artist Pablo Picasso (1881–1973). The work portrays five nude female prostitutes from a brothel on Carrer d'Avinyó (Avinyó Street) in Barcelona. Each figure is depicted in a disconcerting confrontational manner and none are conventionally feminine. The women appear as slightly menacing and rendered with angular and disjointed body shapes. Three figures on the left exhibit facial features in the Iberian style of Picasso's native Spain, while the two on the right are shown with African mask-like features. The racial primitivism evoked in these masks, according to Picasso, moved him to "liberate an utterly original artistic style of compelling, even savage force."<sup>[3][4]

The attached Wikipedia description claims this animal is a ferret; however comparing ferrets to ermine photos makes this guy very much an ermine.
