What do Bri's paintings represent in the play, A Day in the Death of Joe Egg?

For Sheila, Bri's cowboy paintings symbolize his lack of ambition. She believes he would be a more skilled painter if he were more dedicated to his craft. Bri only paints cowboys. One of the cowboys is disabled, a Thalidomide baby. Even Bri's fantasy life incorporates disability. They also symbolize Bri's desire to escape his married life. In Act Two, he thrusts his head and hands through one of his paintings and mimes shooting guns. For a moment, he embodies a cowboy, someone who has as much freedom of movement as Bri longs to have.
