An album of rare and previously unpublished photographs of Princess Diana launching the HMS Cornwall in 1985 is set to be auctioned off later this year.

Princess Diana, born Diana Spencer, was known and loved widely for her charitable work and her high-profile role in the British monarchy. Diana was recognised for her dedication to various causes, including the fight against HIV/AIDS and the support of children's charities. She also worked to destigmatize mental health issues.

After Diana died in a car crash in Paris, a significant outpouring of public grief ensued, and Diana was mourned by people around the world. For reasons such as these, her unpublished photographs are looking to be exceptionally sought after.

The album, entitled "Launch of HMS Cornwall by Her Royal Highness The Princess of Wales at Yarrow Shipbuilders Limited 14th October 1985," includes a total of 38 photographs, both in colour and black and white, and is expected to fetch a price between £500 to £800.

The photographs were discovered in a bookshop in Lewes, East Sussex and will be featured in Charles Miller Ltd's auction, titled "Maritime and Scientific Models, Instruments & Art" which will take place on April 25, 2023.

It is believed that these images, which depict the Princess greeting Royal Navy personnel in Glasgow, have not been previously published as the album was said to have been privately produced for Yarrow Shipbuilders Ltd, and was given to the directors as a keepsake. The photographs showcase Princess Diana, who also held the title Duchess of Cornwall, interacting with members of the Armed Forces, their families, and well-wishers.

HMS Cornwall was launched in Glasgow in 1985 and commissioned at Falmouth, Cornwall, in 1988. The Type-22 frigate was originally designed as a specialist anti-submarine vessel and was decommissioned on 26 April 2011. This album offers a unique glimpse into a momentous occasion in the life of Princess Diana, and an opportunity for collectors and fans to own a piece of history.
