The BBC website reports that this accolade is claimed (by the publisher) for Annie Vallotton.
Who’s Annie Vallotton you might ask?
She is the Swiss woman who illustrated the Good News Bible in the 1970s.
Sample quote:
One of the most memorable examples is of the crucifixion in Luke’s gospel. The thorn-crowned head hangs forward, below the single line of the shoulder. Above it, two right-angles are the cross.
Somehow this plain sketch conveys the desolation of Jesus far more powerfully than two hours of Mel Gibson’s blood-spattered film, The Passion of the Christ.
