Update | Hark saw this post and commented a correction to me saying this seemed to be a picture of Crakow: The image is from WARSAW actually - showing Castle Square with the Royal Castle and part of the Old Town. It doesn't say so on the card, though. Only says where it was printed - and that's the Cracow bit :)
And these are the beautiful, and once again, new-for-me-stamps!
Y estas son las hermosas estampillas, otra vez nuevas para mí.
