One exhibit of note was Beautiful Jim Key, the "educated" Arabian-Hambletonian cross horse in his Silver Horseshoe Pavilion. He was owned by Dr. William Key, an African-American/Native American former slave, who became a respected self-taught veterinarian, and promoted by Albert R. Rogers, who had Jim and Dr. Key on tour for years around the US, helping to establish a humane movement that encouraged people to think of animals as having feelings and thoughts, and not just "brutes." Jim and Dr. Key became national celebrities along the way. Rogers invented highly successful marketing strategies still in use today. Jim Key could add, subtract, use a cash register, spell with blocks, tell time and give opinions on the politics of the day by shaking his head yes or no. Jim thoroughly enjoyed his "act"—he performed more than just tricks and appeared to clearly understand what was going on. Dr. Key's motto was that Jim "was taught by kindness" instead of the whip, which he was indeed.
