OIL PAINTINGS OR WATERCOLORS, once they are detected as being on a photographic base, are composed of a delicate complex structure with the combined characteristics, in many instance, of a textile (the canvas support), paper, photo image, oil paint layer, and a varnish coating.

These portraits are now becoming not only collector's items, but also important historical documents as well as works of art and are acquiring considerable heritage value.


THE AUTHOR WISHES TO EXPRESS his special thanks for their valuable assistance to Stanley G. Triggs, Curator of the Notman Photographic Archives of the McCord Museum, McGill University, Montreal, and his assistant, Norah Hague; Ann Thomas, Assistant Curator of Photography, National Gallery of Canada; Maija Vilcins, Reference Librarian at the National Gallery of Canada; the National Library of Canada, and the Public Archives of Canada, Ottawa.
