Prestonpans six-year-old Jack Henderson might have drawn more than 400 pictures in his incredible fundraising drive, but his latest challenge could be his toughest yet.
For the Cockenzie Primary School pupil has set himself the challenge of drawing 24 pictures in just one day in a day-and-night challenge on Tuesday.
Helping out the young fundraising hero - whose quirky idea has seen him raise nearly £25,000 for Edinburgh Sick Kids Hospital - will be his family: dad Ed, mum Rose and younger brothers Toby and Noah.
Jack's drawathon starts at 1pm and will see him publish a new drawing on his website, jackdraw sanything.com, every hour until the last one has been uploaded at noon on Wednesday.
The drawathon comes exactly one month before a book of Jack's artwork is set to be published. 'Jack Draws Anything: The Little Boy with the Big Art' comes out on October 6 through Hodder Children's Books and can be pre-ordered through Jack's website.
