About Juliusz...
I've signed in here for my 10-year-old son (born in 2012) who wants to be a traveler so a postcard with a landscape of your place and its name is perfect :) he also wants to learn English so please, write few words to him :) he will be delighted!
He also likes maps! So any postcard with a map of the place you live will make him very happy :) He also is interested in geography and other countries if you could write something interesting about your country or place you live like about animals, people and their customs, how children live or what they play in your country, everything is interesting for him and each card is his treasure :)
He is also a guitarist. a football (soccer) player, does karate. He loves music, sports (especially football).
