Have you ever personally seen any stereographs or cartes de visite of the British coal mining or encounterd collectors in your study experience? I would appreciate it very much if you could give me any information or advice. I have been interested in the contacts and conflicts between the working classes and the Upper/Middle classes in the photographic media: stereographs, cartes de visite, lantern slides and postcards. I started to collect them concerning the British coal mining. I bought postcards and have been collecting copies of some stereographs of an American mine, two cartes de visite of Wigan woman workers, and several lantern slides to see in the Museum of Science and Industry in Manchester and the National Coal Mining Museum in Wakefield. I keep inquiring of other Museums and archives, but I have not had encounterd many so far, especially stereographs and cartes are difficult to find. I presume that there must have been less stereographs of the mining industry in Britain than in the U.S. and generally speaking, the purposes of their use were limited in the Upper and Middle classes' study or travelogue, although I have not found any concreate research result on the issue: to what extent the British working classes committed themselves to the stereograph and the carte de visite. (There are some slight references or clues.) ---------------------- [log in to unmask]
