You may be forgiven for thinking that these are stamps from Crete.
And they are. And yet they are not. Confused?
Well, this is how it went: the original stamps are indeed from Crete. They were issued when Crete was still independent. But in 1913 Crete became part of Greece.
Now Greece lived through a period of monarchies, crowned democracies and various revolutions in those days. When in 1922 another revolution had the king abdicate once again, all the remaining stocks of Cretan stamps were overprinted with this "Revolution 1922" plus new value overprint. This, by the way, only happened in 1923.
So they are Greek, although they were Cretan.
So please rearrange your albums accordingly (if needs be, that is).
