From Artnet:
“The Oval Office” political button, signed in the plate, features the same image used in the limited edition screenprint and posters Lichtenstein created to raise funds for the 1992 Clinton-Gore campaign. It was executed for the Artists for Freedom project in order to benefit a number of organizations. These organizations included the Democratic National Committee, the Democratic Senatorial Campaign Committee, the Democratic Congressional Campaign Committee, Citizen Vote, as well as selected candidates. Other participating artists in the cause included art legends such as Joan Mitchell, Cindy Sherman, and Jim Dine. For this pin, as well as the Oval Office print and painting, Lichtenstein conducted research of the interior of the Oval Office, incorporating realistic details such as the paintings on the walls, but rendering the room through the comic-book lens that the legendary Pop artist is now famous for. While Lichtenstein’s works generally comment on art historical trends, this pin allows for a deeper understanding of his personal concerns and how he incorporated his talent and his career in his politically-oriented endeavors. This campaign button was mass produced, numbering approx. 5,000 buttons in total. However, more than 4,000 were confiscated and remain in the archives of the Roy Lichtenstein Foundation. The remaining pins - like this one - are quite rare and highly collectible.
