An artist has set a new Guinness World Record for creating the world's smallest handmade sculpture of a smiley face which is so small that it is invisible to the human eye.
David A Lindon, from Bournemouth, Dorset, in the UK, created the artwork, which measures 0.01104mm by 0.01233mm, which was placed on a single microdot which forms part of the profile of the late Queen Elizabeth II on a first class postage stamp.
Mr Lindon said: "I am thrilled at this news and grateful for Bournemouth University for measuring it.
"My sculpture is so small that it is the same size as a particle of talcum powder, a human blood cell, mould spores, bacteria and even a fog droplet."
Dr Sarah Elliott, associate head of school of life and environmental sciences, said: "Our students will be fascinated to see the sculpture that David has created for us, and we hope that this will inspire students to think of life in miniature in different ways."
The micro-artist was assisted by scientists at Bournemouth University to measure the sculpture which is called Yellow Smiley Face.
He added: "The Yellow Smiley Face sculpture beats my previous world record of the Red Lego Brick sculpture, which is bigger than this and measures 0.02517mm by 0.02184mm."
