In January 1950, Branham's campaign team held their Houston campaign, one of the most significant series of meetings of the revival. The location of their first meeting was too small to accommodate the approximately 8,000 attendees, and they had to relocate to the Sam Houston Coliseum. On the night of January 24, 1950, Branham was photographed during a debate between Bosworth and local Baptist minister W. E. Best regarding the theology of divine healing. Bosworth argued in favor, while Best argued against. The photograph showed a light above Branham's head, which he and his associates believed to be supernatural. The photograph became well-known in the revival movement and is regarded by Branham's followers as an iconic relic. Branham believed the light was a divine vindication of his ministry; others believed it was a glare from the venue's overhead lighting. A copy of the photograph is held in the Library of Congress, Washington D.C.
