Jungholz/Tirol - Austria enclave under Geman economic jurisdiction

 commune - administrative division, enclave, draw only border

The only road access to Jungholz, an Austrian town, is through Germany. The town is politically Austria, but economically German. Prior to the introduction of the Euro in Europe, Austria used schillings as currency, but Jungholz officially used German marks.
The Austrian post office sold Austrian stamps, but customers had to pay for them with German money. Mail to Germany was taxed at internal domestic mail, which was stamped with a special postmark inscribed "Sondertarif" (Special Tarif). Jungholz is within the German customs area - goods from Austria to Jungholz are subject to German import tax.
Same situation applies in the Kleinwalsertal (main town Riezlern), just west of Jungholz.
Now that German-Euros and Austrian-Euros are equal, and given the integration of Europe that has occurred since 2000 (open borders, common customs area, tax harmonization), there is pressure in the Austrian government to terminate the treaties that made these special area arrangements. The situation has normalized life for the rersidents of these areas, and the treaties have really outlived their usefulness.
