 The festival took place from 24 July - 2 August 1975, in the Centenary Palace Exhibition Halls whilst the public Campaigns were in the near-by Heysel Stadium, Brussels.Many well-known evangelical figures first came to prominence at the festival, such as Luis Palau, Bishop Festo Kivengere, Annie Vallotton the French-Swiss Good News Bible illustrator and Manfred Siebald the German singer-songwriter.Vallatton gave a talk each morning before the Bible expositions, that she illustrated on an overhead projector, fitted with an acetate scroll.
