The "Allen Bluff Mule," is a painting of a mule on a limestone bluff on U.S. Highway 70 in Liberty. The mule has been around so long, many residents are unsure of the origin of the mule. Some say a local man named Lavader Woodard painted the mule. Other residents contend that it was painted as an advertisement of a local stock farm.
In 2003 Liberty residents became upset that an expansion of U.S. Highway 70 to a four lane road could threaten the mule painting. The residents started a letter writing campaign to the Tennessee Department of Transportation. Supporters of the mule also placed signs along the roadway stating "Save the Mule." Ultimately the road expansion was far enough away from the mule, that it was never in any danger.
The article "Historian Unravels Liberty Mule Mystery", written by Thomas G. Webb in the November 11, 2006 issue of The Smithville Review, seems to point to Dr. Wayne T. Robinson as the original painter. The Smithville Review's November '06 article points back to an article written by Dr. Robinson in the March 7, 1957 issue of the same paper. Link to November 11, 2006 article transcript:
In this March 1957 article, Dr. Robinson comments,
"In early October 1906, I climbed up the face of the Allen Bluff to a ledge and with some coal tar made a flat picture of a character from a famous comic strip of that day. Everybody remembers Maud, the mule. That was 51 years ago, and even though it has been exposed to the elements and to nearby earth-shaking explosions, erosion has dimmed it very little. On the same bluff is the name of Will T. Hale, which was inscribed about 85 years ago.”
This article seems to verify that Dr. Robinson painted the original mule in 1906 as a 21-year old college student inspired by Maud the Mule, from Frederick Burr Opper's comic strip "And Her Name Was Maud!"
