In 1971, curator Maurice Tuchman's revolutionary "Art and Technology" exhibit opened at LACMA after its debut at the 1970 World Exposition in Osaka, Japan.[46] The museum staged its first exhibition by contemporary black artists later that year, featuring Charles Wilbert White, Timothy Washington and David Hammons, then little known.[47] The museum's best-attended show ever was "Treasures of Tutankhamun", which drew 1.2 million during four months in 1978.
