This is officially the biggest postcard I've ever received ( 21 cm x 15 cm!). It doesn't even fit in my postcard boy so I'll have to think of another place to store it... Maybe I could frame it? :P
We can see Stockholm's Old Town and the Royal Palace from above, with all the bridges, canals and boats that surround it. The Royal Palace is has 1430 rooms, 660 with windows and is one of the largest royal palaces in the world still in use for its original purpose. Thanks to my dear sis once again!
