Yesterday’s Sandwich is a collection of Boris Mikhailov’s “Superimposition” series, created in the late 1960s and early 1970s. Mikhailov utilized a “sandwich” method by intentionally overlaying color slides to create surreal tableaux. These double exposures served as a unique visual language, reflecting the duality and contradictions of Soviet society by juxtaposing mundane drudgery with forbidden subjects like nudity and beauty. The series existed only as projections for nearly thirty-five years before being compiled into this definitive volume.
