However, The authors of "Gettysburg Cyclorama, The Turning Point of the Civil War on Canvas", Boardman and Brenneman present extensive historical research that concludes that the WFU version is not one of the original four done directly under Philippoteaux's direction, but is rather one done under the direction of Austen, using Philippoteaux's drawings, and with many artists from Philippoteaux's studio. Furthermore, they cite newspaper articles showing that what they believe to be the Chicago version was destroyed in a storm in Omaha in 1894, and they also present evidence that Austen directed the production of the WFU cyclorama in 1905. This WFU version was recently featured on WRAL's Tarheel Traveler program.
