Walton's small-scale portrait of his friend Joseph Crawhall shows him in a studio, a clay pipe in one hand, leaning against the back of a canvas. Bullfighting posters are attached to the canvas which is propped against another depicting a bull-fight. They allude to several of Crawhall's artistic preoccupations: Spain, Morocco and animals. The two artists met through Walton's brother Richard who married Crawhall's sister Judith. Walton's main interest was landscape painting but he was also a gifted portraitist and makes humorous reference to contemporary stylistic labelling in his inscription: 'Joe Crawhall the impressionist by E.A.Walton the realist'.
