The first half of the century saw the production, in Vietnam, of thousands of photographic postcards. The portraits and scenes depicted usually included the name of the publisher or photographer. This information was printed on the face of the cards, and shown above is an example from the Raphael Moreau studio. In the interests of photographer identification, it was tempting, therefore, to include here a representative sampling of images. Unfortunately, however, space would permit inclusion of only a small fraction of those available, and the result would have been unsatisfactory given the considerable number of publishers and photographers involved. It was decided, therefore, to include only those postcards which illustrate multiple images. These collages are helpful in that they show, in one view, many examples of the work of the publisher or photographer in question. And given that the images are very often copies of earlier large-format photographs, they can provide researchers with a handy resource, especially when trying to connect otherwise unidentifiable photos with their original authors. There have also been some books published on the subject of Vietnamese postcards and researchers will find them an invaluable source of supplementary information.
