LOUISIANA, Mo. —  Street performers and an audience appear to be having a good time in this undated photo that was part of a collection donated recently to the Louisiana Area Historical Museum by John Wood. The sign on the cart reads “Horse-Mobile Pike County, Mo.” The sign on the horse features the words “You will have to show us.” The museum will be open during the Bluegrass Pickers Festival May 13 and launch its summer season on May 27.
