Ashton's eye was drawn to the multi-coloured masterpieces created by a British artist called Iris Grace, who has been likened to Monet by many of her buyers.
He was moved to express his interest in Iris's work on Facebook.
Iris Grace is five years old, she lives in Leicestershire with her mum Arabella Carter-Johnson and dad Peter-Jon, and she was diagnosed with autism in 2011.
Iris started painting as a way to help with her speech therapy, joint attention and turn-taking. It soon became apparent to her parents that she possessed an extraordinary talent.
"Her autism has created a style of painting which I have never seen in a child of her age," Arabella told Parentdish.
"She has an understanding of colours and how they interact with each other. She beams with excitement and joy when I get out the paints, it lifts her mood every time.
"She has found a way of expressing herself that is so beautiful, so we wanted to share it and thereby raise awareness of her condition, which is currently affecting around 100,000 children in the UK and these numbers are rising."
Iris's original artworks sell for thousands (a piece currently being auctioned has a highest bid of £1,400). But you can pick up a print of one of her pieces for a more reasonable £38 - £92; and greetings cards featuring one of her designs cost just £2.
Ashton's Facebook post has driven a whole host of new admirers to Iris's mum's Facebook page, so expect a sharp increase in bids on her upcoming auctions.
