In a crowded Christie’s auction room in May 2018, Mexican artist Diego Rivera’s 1931 painting The Rivals came to the stage. Commissioned by Abby Aldrich Rockefeller and given as a wedding gift to her son, David, and his new wife, Peggy, in 1941, the work was a small part of the largest auction to date, one that eventually set a record with its $835 million total. Within a few minutes, The Rivals sold for nearly $9.8 million, a record for a Latin American artist at auction (one eventually shattered by Rivera’s wife, Frida Kahlo, in a $35 million sale in 2021).
