Background: This collectible Forever stamp honors beloved American actress and comedienne Betty White (1922-2021), whose impish smile is depicted on the stamp and lit up performances in a career that spanned more than 60 years. Often referred to as the “First Lady of Television,” White was honored with five Primetime Emmy Awards for her work in television, as well as three Screen Actors Guild Awards, a Grammy Award and a star on the Hollywood Walk of Fame. She was also much recognized for her animal welfare work.
The Betty White stamp features a digitally created portrait of the cherished star against a violet-colored background and, in a lighter shade, bubbly spots that befit her sparkling personality. She is portrayed wearing a polka-dotted blue top. “Betty White” is printed in white near the bottom of the stamp artwork. “FOREVER USA” is printed just below, in violet. Her name also appears centered atop the white selvage, also in violet.
Postal Products: The Betty White stamp will be available in panes of 20. As Forever stamps, they will always be equal in value to the current First-Class Mail 1-ounce price.
