Kate, the Duchess of Cambridge, made an appearance outside Kensington Palace to commemorate the launch of the Hold Still book.

In support of the launch, Kate participated in the Book Fairies initiative.

This initiative involves hiding books for people to discover and enjoy.

The Duchess was filmed placing a copy of the Hold Still book near a statue of Queen Victoria in London, allowing royal fans the opportunity to find and collect it.

The Hold Still book features a collection of 100 pictures taken by the finalists of the Hold Still contest.

Additionally, it includes a heartfelt letter from the Duchess herself.

The Book Fairies initiative encourages readers from all over the world to hide books for others to find, read, and pass on.

Kensington Palace revealed that Kate is not the only person to have hidden a copy of the newly launched book in plain sight.

Sharing Kate’s clip, the Royal Household stated, “Let the search begin.

We’ve joined @BookFairies for the day to share copies of Hold Still around the UK with you.”

Each copy is adorned with a gold Book Fairies sticker, gold ribbon, and contains a letter from the Duchess.

To make this activity even more special, Book Fairies, the Hold Still judges, and participants of the final 100 images are leaving copies at locations that brought them hope during the lockdown.

The sale of this unique collection of photographs will benefit mental health charity Mind and one of Kate’s patronages, the National Portrait Gallery.

In the clip, Kate can be seen walking towards the statue in a stunning long red dress and carefully placing the book.

The Hold Still book launch coincides with the one-year anniversary of Kate’s launch of the Hold Still Photography Contest in collaboration with the National Portrait Gallery.

The contest aimed to capture life in Britain during the initial national lockdown.

Out of the thousands of pictures submitted, a panel of judges carefully selected 100 finalists to be included in the book.

These photographs were also displayed on billboards across the country.

It was revealed yesterday that Kate reached out to several finalists in autumn 2020.

The first full video released on the Cambridge’s new YouTube channel features a phone call between the Duchess and four-year-old Mila, one of the 100 finalists.

Mila, who is the subject of the photograph titled “Shielding Mila,” was captured by her mother Linda looking at her father through a window.

During the call, Mila’s family shared their experience of making the difficult decision to separate in order to protect their youngest daughter, who was undergoing chemotherapy.
