A jigsaw puzzle that was a photo montage of Queen Elizabeth II's Diamond Jubilee, took Dave Evans 35 days to complete and looked amazing.

In the blink of an eye, Dave's hard work crumbled to the ground, much to his horror and our delight, as it was all captured on video.

He is now rushing to reassemble it so it could be put on display at Sandringham Estate in May as planned.

Dave is even getting offers of help from people on Facebook.

Luckily for Dave, photos and other documentation for a Guinness world record attempt have already been sent.
