'When asked, as I often have been, who I would recommend as a snuff bottle dealer I am always wary, because this encompasses so many qualities.  Knowledge, empathy, a good eye - and a visionary quality, which is not the same thing - a sensible pricing policy that honestly reflects current values and does not try to extract more from the unwary, a willingness to stand by what one sells and, if necessary, take it back if any material fact proves wrong or mistaken in the light of prevailing knowledge, and, of course, an overall integrity as to the exercise of all of these qualities.
