From Brazil a Card

Postcards show the culture and history of a country.So my friends send me postcards.They also get postcards back.Often when I get surplus cards I send them to other people.This card above came from a young person in Brazil.I received many cards from this person.
So to make your region famous you could send me cards.Details will be given if you ask me.Please note that cards common in your area are very rare in other places.This can be genuinely used  as  a good business venture.Imagine your town has no buyers of cards but there are buyers of these same cards elsewhere.
