 Upon Hickman's death in 2007, a tribute was made by Eddie Bernice Johnson, a representative of Texas, to the House of Representatives.The tribute comments on Hickman's “irreplaceable contributions he made to the community of Dallas and the state of Texas.”

Since his retirement, much of Hickman's work has become available through an array of archives, such as the Briscoe Center for American History, which has been set up by the University of Texas.This particular archive mirrors much of Hickman's work depicted in his published book, "Behold the People," but includes series of photographs succeeding the book's publication in 1994, documenting photographs from 1945 to 2005.
