While I"m in thew writing mood, I thought I'd contribute an illustration
from my specialty, which is the postal history of enclaves and exclaves.

With the advent of the Euro, there will be effects on the "Sondertarif"
cancels used in Jungholz and the Kleinwalsertal. Up to now, Austrian
stamps were sold in the post offices in these places, but in German
currency, which is going away. Up to now, local postage rates applied
both to Germany and Austria - mail to neither treated as international
mail at POs here. So that German postal workers didn't tax postage due
on incoming, apparently "short paid" mail to Germany with Austrian
stamps, cancellation marks are used with the word meaning "Special
Tarif".

The same wording works on mail from Buesingen to Switzerland, which is
illustrated in the accompanying graphic. This mark will continue in
use, given the Switzerland is keeping its Franc. In the Austrian
exclave and customs excluded zone of Kleinwalsertal, Austria intends to
"bring them home to the Reich". With both countries using the Euro, it
is only a short leap to unifying postal tarifs and a customs union
between the two; making this "Sondertarif" process moot.

Get your examples now - a tangible piece of life in enclaves is going
away.
