A live auction titled Reflections on Pop goes ahead on October 7, followed by an online sale that closes on October 9; together they offer one of the final batches of prints from Dorothy and Roy Lichtenstein's own collection. Sotheby's has paired the two sales with an extended collecting guide on how the artist worked in print and what drives value today. The guide treats Lichtenstein's prints as central to his practice rather than as copies of his paintings. After starting in the early 1960s by rubbing Ben-Day dots through stencils, he moved into screenprinting and spent decades collaborating with ambitious American workshops: Gemini G.E.L. in Los Angeles, Tyler Graphics in New York, Graphicstudio in Tampa and Saff Tech Arts in Maryland. His first Gemini project, in 1969, reworked Monet's Haystacks and Cathedrals as flat, mechanical patterns. The 1990 Reflections series was his most demanding technically, layering lithography, screenprint, relief, metallic collage and embossing to simulate the glare of glass over comic-book imagery; the large sheet Reflections on Minerva is estimated at $60,000-80,000. Specialist Chanler Rutherfurd singles out the late Water Lilies, screenprinted in enamel on stainless steel so the metal flickers as the viewer moves; one work from the series required twelve colors across eight screens in an edition of 23. More accessible entries include a 1993 Water Lily at $15,000-25,000 and a well-preserved 1965 Brushstroke sheet at a similar range, while rarities range from a 1956 Ten Dollar Bill lithograph in an edition of 25, described as his earliest proto-pop print, to a study for Reflections on The Scream. She cautions buyers to examine condition closely, particularly fading reds and yellows, and to be wary of fakes among the unnumbered 1960s ephemera. Sotheby's says its sales of works from the estate since November 2024 have transformed the market for Lichtenstein's prints, with every estate print offered so far sold, many at records, and a knock-on effect lifting private consignments as well. Four days after the live sale, the Whitney Museum of American Art opens Roy Lichtenstein: Like New, a 130-work retrospective that includes prints.
