These postcards were the subject of an academic study in 2006, 2007 resulting in four academic presentations and papers published in Canada and Denmark. The study was by Dr. Karen Malcolm, University of Winnipeg, and Barbara J. Becker, Linguistic Consultant. We looked at the text messages on the back of the postcards as well as the visual message on the fronts of the postcards. A link to the online Denmark paper is included.
Along the way, I learned a lot about Edwardian Scotland.
