In 1810, on the 1st of March, was born Frédéric François Chopin, the very famous polish composer and virtuoso pianist. I don't think I need to detail who he was. Two hundred years later, on the 21st of July 2010, the postal administration of Uruguay has issued a svouvenir sheet to celebrate the 200th anniversary of his birth. This is this souvenir sheet that one of my philatelic contacts in Uruguay has used to frank a cover he sent to me.
The other stamp on the cover is a very different one. It was issued on the 10th of October 2000 in a set of two stamps that are part of the UPAEP set. Here is the full set.
UPAEP stands for "Unión Postal de las Américas, España y Portugal" in Spanish, a postal union between states from Americas together with Spain and Portugal. The UPAEP contains 27 members: Argentina, Bolivia, Brazil, Canada, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, USA, Guatemala, Haïti, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Salvador, Surinam, Uruguay, Venezuela, Netherland Antilles, Aruba, Spain and Portugal.
Since 1989 some of the members of this union issue a stamp with a common theme (very similar to the EUROPA stamp issue). In 2000 the theme was Campaign against AIDS as you can see on the stamps of Uruguay. In 2000 seventeen members of the organization have participated to this issue.
For the record the theme for 2010 was "National symbols" and in 2011 it will be "mailboxes".
I think that the stamp picturing the "tic tac toe" game against death is rather striking!
To be noticed also on the cover the large rectangular postmark.
