Audrey Irmas, a longtime donor to Los Angeles art museums and Jewish causes, will sell a large 1968 “blackboard” painting by Cy Twombly that she's owned since 1990 and use $30 million of the predicted auction proceeds of more than $60 million to help build a new events center at the Wilshire Boulevard Temple in Koreatown.

The 55,000-square-foot Audrey Irmas Pavilion will be designed by the Office for Metropolitan Architecture, the firm led by noted Dutch architect Rem Koolhaas.
