Aland Islands - Think Green - Europa stamp

Susanna Mylly of Finland went on a tour to Aland Islands. Since Aland has issued 2 "Think Green" stamps in accordance with the Europa theme of this year,  I requested for the one which is different from the common one.  She was kind enough to send me the requested "Think Green" stamp with a special cancellation "Kastelholms Slott". Slott in Swedish means Castle, Kastelholms is the name of the district in Aland, where many historical events took place.  You can learn more interesting facts about it here. Thanks a lot Susanna Mylly, Nice addition to my "Around the world Cards and Covers Collection".
