A hitherto undiscovered technical drawing by Leonardo da Vinci is set to go under that hammer at top auction house, Crufts, later today.
The drawing, believed to be a set of plans for an early version of a helicopter, was discovered in the loft of a house in London's trendy Peckham by the house owner, Wilma Princecombe, she told us:
"I was up in the attic rootling about like you do when I found the drawing. I immediately thought that it looked like plans for a helicopter or sumfink like that. I knew Leonardo da Vinci used to be a lodger here back in the twenties when he wrote that code book thing and I put two and two together, called Crufts and here I am"
Experts expect that the drawing will fetch a cool 6 million and that Wilma will be made for life as a result of her lucky discovery.
