Pupils from a Keighley school helped achieve a Guinness World Record title for the most artists working on the same art installation.

The eight children from years five and six at St Joseph’s Primary participated in a project called Face Britain.

They were among 201,948 children and teenagers across the nation involved in the initiative.

They achieved the record by creating self-portraits and uploading them onto the Face Britain online gallery.

At the end of the year, they will become part of history when the entire collection of portraits is handed to The British Library, providing a snapshot of the 2012 generation.

The children’s self-portraits were combined to form an image of The Queen, which was projected on to Buckingham Palace for three nights in April, to coincide with Her Majesty’s birthday.

The Queen’s image and children’s portraits were also showcased on the national network of BBC Big Screens/Olympic Live sites, and on JCDecaux’s network of digital advertising screens in railway stations and shopping centres.

The self-portraiture project was sponsored by B&Q and developed by The Prince’s Foundation for Children & the Arts, which is an educational charity.

Learning mentor Jenny McGuinness, from St Joseph’s Primary, said: “It’s been wonderful to be involved in the UK’s largest ever art project and great to know that the portraits will become part of history. It’s so exciting to learn that our pupils have become record-breakers as well.”

Jeremy Newton, chief executive of The Prince’s Foundation for Children & the Arts, said: “This would not have been possible without the children and young people.

“Face Britain encouraged participants to explore their creativity, and to consider their own identity and place in history during the lead-up to Jubilee and Olympics.”
