Larry Bell's SF 6.21.12B combines vapour coated materials with collage elements on canvas board, reflecting the artist's ongoing experimentation with reflective and translucent surfaces. Created in 2012, this mixed media work demonstrates Bell's sustained interest in light, perception, and material innovation that has defined his career. The incorporation of paper collage with vapour coating techniques creates complex visual interactions and spatial ambiguities. The title suggests a specific reference point, possibly indicating location, date, or sequence within a series. The work exemplifies the contemporary extension of Bell's Light and Space aesthetic into new material territories.
