Cute cat illustration
Why it's important: When Gustav Klimt started out painting his famous work, "The Kiss," it was actually supposed to be "The Cuddlers," featuring these cats. Unfortunately, Klimt was rotten at drawing kittens and he accidentally started creating two humans in an awkward but elegant embrace. The elegance and flow of the painting is all owed to the kitten inspiration. Anyways, Klimt never attempted to paint kittens again.
