There is only one mural in Elkhorn that I know of, it's on the side of the building for Uncle Hunk's Junk, an establishment I have never entered.
The mural is pretty high falutin' for a "junk" shop. I couldn't find an artist name. I was just happy to find a mural on my route to Kettle Moraine for a hike. More about that tomorrow! Linking up to Mural Monday, see what everyone else found if you like.
