This February marks the 100th anniversary of the appearance at Liechtenstein\’s then five post offices of the first three Liechtenstein definitives. These stamps, printed on chalksurfaced paper and with face values 5, 10 and 25 Heller, bore the image of the then reigning Prince Johann II of Liechtenstein (1840-1929).The inscription \”K.K. Austrian Post in the Principality of Liechtenstein\” referred to the fact that the Liechtenstein Post Office established on 1st January 1912 under an agreement made in October 1911 remained under Austrian administration.
With this special issue Philately Liechtenstein highlights the special anniversary. The graphic designer HP Gassner showed on the stamps the four Princes who have reigned since the appearance of the first Liechtenstein stamp, each portrayed against a differently coloured background on which the years from 1912 to 2012 appear in Roman numerals: Johann II, known as \”Johann the Good\” (face value CHF 1.00), Franz I (face value CHF 1.40), Franz Josef II (face value CHF 2.20), Prince Hans Adam II (face value CHF 2.80).
