Varieties Known to me and shown on this web site are Emperador Administrative District 1907-1908, Empire Administrative District 1911-1912 and Gorgona Administrative District 1911-1912. I would think that other administrative districts and dates also exist. I would appreciate from anyone who knows of other varieties.
Function This dog license may have been issued due to the tight controls imposed under the direction of Col. Gorgas to prevent disease. I would appreciate from anyone who can add anything to the history of this piece.
