I'm Sonja from Berlin.
My hobbies are reading (fantasy/SF), my computer and just walking around the city or in the nature.
When I visit a town, I usually go to the churches (not because I'm religious, I just like the architecture) or to offside places. So if you have cards of not so famous sights or religious places or buildings, I'd love to see them.
I also like UNESCO WHS, seasonal cards (in the season), Kaj Stenvall, maps or something really strange/bizarre.
But EVERY card (even a nice or interesting ad-card) is fine, as long as you think it's fine. I'm not too fond of cute animals, though.
And could you please write the date on the card?
