One thing that I found charming about Buenos Aries was the house numbers on the buildings. These are white clay oval markers with the number painted on in black in a rather Victorian font.

I would love to have one as a keepsake (ideally with my office number on it - so I can be cheered up at work). When I was down there I was told however that:

1) They are antiques
2) They are therefore expensive
3) This also makes them illegal to export - and if you're going to rot in prison, you want a more colorful reputation than "the stupid gringo that tried to smuggle an address marker out of the country" if you want to survive.

It occurs to me, however, that it is very likely that someone makes decent replicas that are both relatively inexpensive and unlikely to end up with a roommate named Sr. Bubba). Does anyone know of a source for these?
