I recently purchased a bundle of German medals online. I am familiar with all but this one which is titled, "Wilhelm II Deutscher Kaiser" on its front side. I know that similar coins or marks exist that share the same imagine of the Kaiser on the front side, however this item has a loophole as if its a medal, and its back is a complete mystery to me. The backside depicts a picture of a festival or "festhalle" as labeled under the picture. Surrounding the picture is the phrase, "einigkeit ein festes band hält zusammen leut und land". I am completely baffled by this object as I do not even know if its a coin, medal, or perhaps just a trinket from a festival in Germany during the time. Can anyone shed some light into what this object might be? Thanks!
