Black and white archive film with original commentary explaining the methodology behind double-image painting. The film shows Evan Walters painting a figure of a model using this technique. Presenter Kim Howells interviews conservation officer Emma Fisher at Swansea's Glynn Vivian art gallery in front of one of Evan Walters's double-image paintings 'Stout Man with a Jug', painted in the 1930's. Emma explains how parts of the image are repeated - hand, eye, etc. and that this gives an effect of movement. She suggests that this may have been his response to the experimentation taking place in art at the time; ie his stab at modernism. Emma shows one simple step in cleaning a painting of this age and condition, simply using a cotton bud and a little saliva.
