Passports From Countries That No Longer Exist

Tom Topol has been collecting passports for 14 years, and runs the website passport-collector.com, a repository of travel documents through the ages. Atlas Obscura has posted six passports from Topol's collection that are from countries that no longer exist because they switched names, changed hands, or disappeared altogether.

The passport above is from the German Empire which was comprised of various duchies, principalities, and free cities—including Duchy Saxe-Coburg-Gotha, which issued this green passport to one of its citizens in 1916, four years before it was absorbed by Bavaria. I like it because the dog is included on the document.
