Christie’s Private Sales will present “SLG Forever,” a fundraising exhibition for the South London Gallery, from June 5 to June 24, 2026, at its London location, with online viewing extended through September 30. More than 25 British and international artists, including Alvaro Barrington, have donated works to support the SLG’s 135th anniversary-year initiatives, which include upgrading its historic main gallery, commissioning new works, and expanding its Communities & Learning programs. Proceeds from sales will benefit the institution as it marks its 135th year and Director Margot Heller’s 25th year in the role.
