National Doodle Day, on February 27th, is a UK-wide campaign of fun which aims to get the nation doodling and raise hundreds of thousands of pounds for The Neurofibromatosis Association and Epilepsy Action. They are currently auctioning 341 items on eBay to raise funds - most of which are doodles, one of which is a drawing of a car by Nick Mason, on the reverse side of an official National Doodle Day card.
