In the 1860's Turkestan came under the control of the Russian
Empire as is reflected in this map, circa 1914
In Les Timbres de Fantaisie Georges Chapier notes that around 1921 a cinderella issue appeared for Turkestan with spelling and currency suggesting Russian origin (60). He records the following denominations and designs:
5 koh denomination
Chapier only documented imperforate varieties of this issue. Modern Russian catalogues indicate that the stamps exist in both perforated and imperforate varieties and that there are several overprints. They attribute these fantasy issues to printers in Paris or Italy and date them in 1923 or 1924 (Langenberg).
