Throughout the 1980s, Howson, who had spent time in the army and travelling before returning to Glasgow, became known for his depictions of working-class life which told stories of economic hardship and social tension.
He became the official British war artist for Bosnia in the 1990s, where he created some of his most-talked about works, including The Massacre of Srebrenica.
Muir said: “Peter is one of the greatest living artists of our time, and I’ve looked up to him since the day I first picked up a brush.
“You can’t escape his influence in the Glasgow art scene – his work is everywhere, in the best collections and in every conversation about painting.
“And when you finally see a Howson piece in the flesh, you understand exactly why.”
The background of the artwork echoes Van Gogh’s Starry Night with two suns hanging in the sky that aim to represent the meeting of the two artists and their styles.
“Two Sons is both of us on the canvas, exactly as we are,” Muir added.
