Children at the St Neots school created self portraits and that were combined with others from around the country to form an image of the Queen, to set the title for the most artist working on the same art installation. The image was projected onto Buckingham Palace for three days for Queen Elizabeth IIs birthday and will be shown on 200 screens in train stations and shopping centres across the UK until the end of the year. After that the portraits will be handed over to The British Library. Nicola Hill, a teacher at the school, said: Its been wonderful to be involved in the UKs largest ever art project and great to know that the portraits will become part of history. Its so exciting to learn that our pupils have become record breakers as well. This is the second Guinness World Record our pupils have taken this year. In March, our school choir joined with the 6,000-strong Young Voices choir at the O2 Arenain breaking the record for the largest live performance. Its been a great ear for us in the arts so far. The previous world record was held by 28,267 artists in Tel-Aviv in 2009 who produced a piece that resembled the Israeli flag using fingerprints.
