Tobey's works and highlights of SAM's Asian collection were featured under the museum's aegis at the Century 21 Exposition (the 1962 Seattle World's Fair). A Jacob Lawrence retrospective in 1974 honored a giant of African American art who had settled in Seattle four years earlier. Leonardo Lives (1997) featured the Codex Leicester, the last manuscript of Leonardo da Vinci in private hands, which had then been recently purchased by Bill Gates.[16]
