Tolkien wrote his last letter to Priscilla in August 1973. She was, until her death, the
honorary vice-president of
the Tolkien Society. She wrote an article titled "My Father the Artist" in December 1976 for
Amon Hen, the bulletin of the Tolkien Society. After her eldest brother, John, returned to Oxford in 1987, the siblings began identifying and cataloging the large collection of family photographs. In 1992, she and John published the book
The Tolkien Family Album, containing pictures of the Tolkien family, to celebrate the 100th birth anniversary of their father. The same year she unveiled a plaque at the Anglican
Cathedral of St. Andrew and St. Michael commemorating the hundredth anniversary of her father's birth at
Bloemfontein, then in the
Orange Free State. She launched the special Tolkien edition
Royal Mail stamps commemorating her father's works in February 2004. In 2012, she, along with a coalition of British publishers, sued
Warner Brothers for US$80 million in her capacity as a trustee of
The Tolkien Trust, accusing them of exploiting Middle-earth characters to promote online gambling. == References ==
