In a clip shared to Prince William and Kate’s Instagram account, the Duchess, dressed in a red coat, was seen placing a copy of the book outside Kensington Palace.
The caption read: “Let the search begin! We’ve joined @bookfairies_uk for the day to share copies of Hold Still around the UK with you.
“Each copy is adorned with a gold book fairy sticker, gold ribbon, and has a letter from The Duchess tucked inside. To make this activity even more special, book fairies, the Hold Still judges and participants of the final 100 images are leaving copies at places that gave them hope during the lockdown.
“This special book documenting the unique collection of photographs goes on sale today in UK bookshops and online.”
Recordings of the phone call the Duchess made with finalists of the Hold Still community photography project have also been shared on the royal couple new youtube channel
The Duchess took part in a phone call with Lynda Sneddon and her four-year-old daughter, Mila, whose photo was included in the project.
During the call recorded in autumn 2020, Kate made a sweet promise to the little girl that she would wear a pink dress when they were able to meet.
Net proceeds raised from the sale of the book will be split between leading mental health charity Mind and the National Portrait Gallery. The funds will help to support arts and mental health projects across the UK, including Mind’s work in local communities and the National Portrait Gallery’s education and community projects.
