She sow had a nose for art. Pigcasso, the wildly talented pig who sold over $1 million of her paintings and was hailed “the most successful non-human artist in world history,” has died at age 8. Joanne Lefson, the creative critter’s owner, recently announced the 450-pound visionary’s death due chronic Rheumatoid arthritis. Prior to her passing, the pig’s illness rendered both of her back legs lame, owing to calcification of her lower spine.
