Some artists like to sign their names on the reverse of their paintings rather than on the face. Notably, Georgia O'Keeffe, Adolph Gottlieb, and Balthus, among others, always used the back of the canvas to put their signatures, date, and sometimes the place where the work was created. Oskar Kokoschka used the entire back of one of his self-portraits to write: Looking out of the picture am I, looking at me are you, 24 Dec. 1914 (in German). To preserve such important details, the author has utilized modern materials to develop his technique of transparent linings. The original system is described, and more recent materials and methods were added. A shortened version of an actual Conservation Report is given. Transparent linings are important for another reason as well: as do x-rays, they show any mistakes which might have been made during previous treatments of a given painting.
