Eleven artworks by the brother and sister duo will be part of the auction’s offering, with two being presented during a live sale on April 14, and nine to be included in the 20th-century art online sale being held from April 7-19.
In 2014, Christie’s Dubai set a world auction record for Effat, for selling one of her portrait works painted in the early 1960s for $62,500. 
Her brother’s work also set an auction record in 2015 for “The Temple of Karnak,” painted in the 1930s, selling for $62,500 during Christie’s Dubai Middle Eastern Art auction.
