This catalogue presents Lichtenstein's entire oeuvre. Artworks have been classified primarily by technique, e.g., drawing, followed by sub-classifications based on materials, e.g., drawing (pastel) and function, e.g., drawing (color separation).
Where applicable, we distinguish between unique and editioned works within the same classification, e.g., sculpture (unique) and sculpture (editioned).
The acetate and Rowlux/plastic classifications were defined by techniques specific to Lichtenstein.
In-depth notes have been added for a selected group of classifications, to be expanded in the future.
