Top: "Portrait of a Stallion" by Albert Bierstadt. Here's a fun fine art anecdote. Bierstadt, among the most revered romantic painters of his time and icon of the Hudson River School, completed the sketch of the white stallion as part of his quest to gather information for his masterwork, "The Last of the Buffalo." The latter is a showcase work and part of the permanent collection at the Whitney Gallery of Western Art at the Buffalo Bill Center for the West in Cody, Wyoming. The sketch, remarkably, is also in the collection. Images courtesy Whitney Gallery of Western Art.
