Not for Estonia.
Estonia was part of the Russian Empire until the end of the first World War.
It was independent until the start of the second World War, and was occupied by Germany and later on the Sovjet Union, until it regained independency in 1991.
Since the first stamp was printed in 1919, it's not really a difficult stamp to find, and above that, it's not an expensive stamp at all.
The stamp is unperforated and is part of a set of 4.
The second stamp also was emitted with perforation.
