“They were in a photograph taken in 1921 which we found in a picture library…. I very carefully photographed Jack, matching the angle and the lighting of the 1921 photograph, and shooting him from different distances too, so that his face would be larger and smaller on the negative. This allowed the choice of an image size which when enlarged would match the grain structure in the original photograph. The photograph of [Jack's face] was then airbrushed in to the main photograph, and I think the result looked perfect…."
The photo of Jack is not real. His face was airbrushed onto someone else's body.
