Gimnazjum nr 12 in Poland greets pupils from other countries who have exchanged postcards as part of a project to learn about other European cultures. The school has received over 30 postcards from countries including Germany, Greece, Turkey, Slovakia, Iceland, and Spain. Some students describe the postcards they found most interesting, such as ones from Iceland about polar auroras, from Germany about Hamburg, and from Greece about its population and monuments. The students say they have learned a lot from the postcards.
