	None of the above portraits exist. They were created by placing point models on samples of each painters work and computing the PCA of both the shape and the appearance. Each image is the mean shape coloured with the mean appearance. ~~They are arranged in date order~~: Giotto (~1300), Leonardo da Vinci (~1600), Valazquez (~1630), Rembrandt (~1650), Modigliani (~1900), Soutine (~1930).
