The gorillas are good and the rhino is respectable, but the best animal artist at the Denver Zoo is clearly Dolly, one of two painting pachyderms that show their stuff every so often for special events and fundraisers. Despite Dolly's partially paralyzed trunk, her work stands out for its expressive palette and an abstract style that can evoke a variety of emotions, from anger to nostalgia to a desire for more peanuts. Bravo, Dolly!
