Wragg illustrated biblical texts in a politicised way, notably The Psalms for Modern Life (Selwyn & Blount 1933) which went through several reprints.
The simplified block-style and dramatic chiaroscuro effects of these illustrations make them resemble woodcuts rather than pen and ink drawings (misleading some collectors into thinking the books were reissues of hand-printed original editions).
He blended social realities and symbols to convey deprivation, justice, conscience, and the persistence of spiritual values in the alienated urban-industrial environment.
A friend and follower of pacifist preacher Canon Dick Sheppard, Wragg became a sponsor of the Peace Pledge Union and was a conscientious objector during World War II.
