This is an example of a wire watermark. It consists of a circle inside of which appears to be a horned animal with open mouth. Its eye is prominent and a curled tail is noticeable. At the top of the circle, on its outside surface, is what appears to be a cross, similar to the one used by the Eastern Orthodox Christian Church. In addition to the above watermark, another one appears on the pages of this book. Shown below, it consists of lettering forming the word: "WOHLRAB" in which the "H" and the "B" are shown in lower case while the rest of the letters are shown as capitals. Wohlrab is a a German surname, and might have been the name of a local papermaker.
