1905-15 PPCs to Australia from various towns including two of the Azerbaijani Oil Fields used from Baku (both with messages in Esperanto) & one that is actually Bulgarian, one with a whimsical addition of a man dangling from a dirigible!, a real photo card of a family outside their very fine dacha that probably ended up home to some offensive vodka-swilling Bolshevik, some soiling. A handy lot.
