Comedian and art lover Bill Bailey matches foster carers Marva and Lionel with a young artist to create a stunning portrait of the deserving couple. Marva and Lionel decided to make a difference by becoming foster parents to teenagers looking for a loving home. Thirty years later, they have fostered almost 200 young people in need. The task to capture Marva and Lionel on canvas falls to Manchester-based artist Chloe Cox. The self-taught painter has had a meteoric rise and has already been commissioned by the King and the Windrush Commemoration Committee. Now, she is on a mission to make the people we see on gallery walls more representative of society. What will Marva and Lionel make of the finished work?
