Patsy Cline's voice perhaps is the most unforgettable of any of the stars shown on these stamps. At the time of her death in a 1963 airplane crash, she was the nation's most popular female country music artist. Her unique style forever changed the flavor of country music. Cross-over hits like Walking After Midnight, Crazy, and I Fall to Pieces are still popular today. She remains one of the best-selling female country artists of all time.
