France is totally out of the question and even though I can not find "Themal" anywhere, a third person in Austria said it was a casino connected to Nemzeti (National) Casino during June and July and catered to the British. Though I am not giving up just yet, the Hungary lead sounds good but I will have to dig deeper and find out why there is no Thermal name. One woman said there were two casinos outside of Pest during a period when the land was being developed for spa resorts and, even though none of the postcards I can find doesn't even come close, they were very interested in buying the piece. They are numistmatists and dropped a few names which anyone can do...
