Results from shortwave infrared reflectance imaging spectroscopy of Picasso’s The Tragedy (1903). False–color infrared reflectograms of three detail sections from The Tragedy (top row of a, b, and c). Each image shows a selection of the three spectral band images that best reveal the various underdrawings and caricatures on the panel. Reflectance spectra (bottom row of a, b, and c) taken of adjacent sites that are directly over or right next to an underdrawing line are displayed below their corresponding image
