Oprah Winfrey portrait revealed at National Portrait Gallery

Oprah Winfrey was honored with a portrait at the Smithsonian's National Portrait Gallery on Wednesday, joining the ranks of the Obamas, Harriet Tubman and George Washington. 

The media mogul famously hosted "The Oprah Winfrey Show" out of Chicago for 25 years. And her portrait, which shows her in a purple gown at her California home, was painted by Chicago-based artist Shawn Michael, who grew up watching the show, according to the gallery. 

There are several other symbolic elements of the portrait. The purple gown is meant to symbolize "The Color Purple," the 1982 film she starred in based on Alice Walker's novel by the same name. She is also surrounded by 12 oak trees – symbolizing the 12 disciples integral in her faith.
