Paisley-born John Byrne has combined several careers - playwright, theatre designer and artist. In his most famous play, 'The Slab Boys', Byrne drew on his experience as a paint mixer in a Paisley carpet factory. During the 1980s Byrne wrote the cult television series 'Tutti Frutti', followed by 'Your Cheatin' Heart', which used country and western music as a backdrop to a comedy of Glasgow life. This contemplative portrait is one of a series taken by David Eustace to help his friend, Glasgow-based fashion designer Deryck Walker, with an advertising campaign. Eustace felt some character was needed and so persuaded Byrne to model.
