Thanks to opengameart.org user ryan.dansie for his public domain Round Animals Pack that I used to create the game pieces. The title background is by David Ball from July, 2005, and was found in the Wikimedia Commons. His description reads: "A pastoral farm scene on the Old Mission Peninsula near Traverse City, Michigan. The barn was built in 1912 by Floyd Jamieson. (ref: Evelyn Johnson, Barns of Old Mission Peninsula and Their Stories, 2007, Book Marketing Solutions, pp. 70–71.)
