MERCURIUS REFORMATUS, OR THE NEW OBSERVATOR, London, England, 1691. A quite uncommon newspaper done in question/answer format, whereby a topic, or topics, is raised and then discussed. A singlesheet issue measuring about 8 by 13 inches, in very nice condition. A quite rare title! Note that the photo is "generic" and the issue you get will not have these specific photos or be of this specific date but will have the format as shown.
