The cat wasn’t the only muse of late 19th and early 20th century artists. Creative artists turned six-hundred-pound pigs into graceful tutu-wearing dancers, opera singers and refined butlers. Publishers, including Raphael Tuck & Sons, frequently chose anthropomorphic pigs for the cover of their Christmas and New Year’s cards, and pigs were frequently drawn with four-leaf clovers to symbolize wealth and good health.
