6 1/4 by 3 1/2 inches. It is definitely a Palmer Cox (Brownies) inspired musical wooden instrument - commonly referred to as a pan pipe. It is also inspired by the World's Fair craze in the United States. You can also enjoy the fact that there is an early version of Uncle Sam (very trim), handling over something to a uniformed person. The patent date is August 10, 1889. Plays nice. Wear to the paper as you can see from the photos. Just a cool piece to add to your collection.
