Introduction

For Polish philatelists means "polonica" the issues from foreign postal authorities, that contain a thematic reference to Poland. Polonica concerns stamps, postal cards, postmarks, and first-day-covers.
The link with Poland can be made in various ways. A famous person of Polish origin can be represented on a stamp. For instance Chopin, Copernicus or Madame Curie. Also historical events can be a reason to a polonica issue. The fact that Poland and nine other countries joined the European Union was in 2004 a reason for many countries to issue a commemoration stamp.  

This catalogue contains only polonica stamps, no postal cards, postmarks, or first-day-covers.
Excluded are also:

• Stamps, engraved or designed by Czesław Slania. These stamps are considered as a separate item. The only exception is made for some sheetlets with a text on the frame, remembering the artists jubilee.
• Stamps of the Freie Stadt Danzig (1920-1939), the Generalgouvernement (1939-1944) and Deutsches Reich (until May 1945). Many of these stamps show buildings in cities that now belong to Poland, but in that era belonged to Germany or were occupied by Germany. By issuing these stamps the German authorities surely had not the intention to focus attention on Poland or Polish culture.
