The presentation below outlines evidence for two Sister Lucys using three lines of argument that Sister Lucy Truth has accumulated: historical, photographic, and handwriting. It begins with an “audience experiment” since it was prepared to accompany presentations to audiences who have not yet been exposed to the hypothesis of two Sister Lucys. We believe that the juxtaposition of photos of Sister Lucy I and Lucy II to any open-minded individual will clearly demonstrate an undeniable difference between the two individuals.
