I was thrilled when Suzana agreed to swap with me! She was offering cards postmarked with the special cancellation from Czech Republic. She had many cards to choose from which wasn't easy. This night view shows Wenceslas Square in Prague. She wrote the post office as pictured in the first link is just minutes from this spot. I didn't know that when I selected it - neat! I also wasn't aware this was part of a UNESCO site.
