Lorenzo Ghiglieri has mastered the art of detail in all his magnificent sculptures but "Cantankerous" features a rare bit of whimsy. Ghiglieri, who is an adventurer in addition to an artist, actually has had several personal encounters with grizzly bears on his many trips to Alaska. In addition to the powerful features of the great grizzly, look closely and you'll see a tiny field mouse that seems to be inciting the bear's ire.
