On October 22, 2012, the United States Postal Service announced the issue of a souvenir Forever stamp sheet honoring Lady Bird Johnson as a tribute to her legacy of beautifying the nation's roadsides, urban parks and trails. Five of the six stamps feature adaptations of stamps originally issued in the 1960s to promote planting in public spaces. The sixth stamp features her official White House portrait, a painting of the First Lady in a yellow gown, by Elizabeth Shoumatoff. The stamps were dedicated on November 30, 2012, at the Lady Bird Johnson Wildflower Center of The University of Texas at Austin.
