French-Canadian artist, Louis Boudreault, is known for creating portraits of famous historical figures from images of the person as they were as a child. He layers large amounts of newsprint (I think) onto board to create a substrate which he then uses to create his portraits – these are generally very large paintings. His use of collage, paint, graphite and other media to create the images is fascinating. However I could not find very much information about his technical process and that was frustrating as I really love this work.
