Very special: a postcard with a picture of the participants of the Staunton World Chess Tournament 1946 in Groningen with the signatures of the 20 participants on the back.
This tournament was the first major international chess tournament to be held after World War II. It was also the first tournament in which a number of Russians participated.
Botvinnik won the tournament. Max Euwe was second, Smyslov third. For the signatures of these 3 players: see pictures 3, 4 and 5.
Picture 6 shows the tournament table with the list of participants and the results
The postcard is a bit creased and has a small tear at the bottom.
