The Duchess left a copy at the Queen Victoria statue outside Kensington Palace Gardens in London on Friday.
In a tweet on the Cambridges’ social media account, Kate wrote: “Let the search begin!
“We’ve joined @the_bookfairies 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.”
She added: “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!”
Fans of the Duchess hailed Kate on Twitter for “such a lovely idea”.
One social media user tweeted: “This is such a delightful concept! I love all of your ideas and admire how you bring each to fruition.
“Your creativity & originality shines brilliantly through all you do!”
Another user wrote: “Love this idea! This is definitely one of my favourite projects Catherine has done. Congratulations to everyone involved.”
A third user posted: “Again and again this wonderful woman continues to make the world a little brighter by bringing some much needed fun into everyone’s lives, especially after such a very difficult year.
“Thanks so very much your HRH. Well done!”
Kate launched the Hold Still project in May 2020 to encourage people to take photos to capture the “spirit of the nation” during the pandemic.
