Yoko Ono is recreating John Lennon's famous billboard peace protest for the digital age - she's produced a downloadable version of his "War Is Over" poster in 100 different languages.
The late Beatles legend hit headlines in 1969 when he and Ono rented hoardings at major tourist hotspots in 11 cities around the world to spread their message of peace.
The couple designed a simple black-and-white poster with the words, "War is over! If you want it. Happy Christmas from John & Yoko", which was displayed in cities including New York, Los Angeles, Paris in France, Japan's capital Tokyo, Hong Kong, and Amsterdam, Holland.
Lennon later used the message in the lyrics of his 1971 Christmas single Happy Xmas (War Is Over), and Ono has now revisited their famous stunt, urging fans to download a copy of the festive message from her website, imaginepeace.com.
She writes, "Dear Friends, Download, print & display these posters in your window, school, workplace, car and elsewhere over the holiday season. Send them as postcards to your friends. We say it in so many ways, but we are one. I love you! Yoko."
