Groups Swap - Lookea from Poland

The last of the four cards from the "12-12-12" postmark swap I participated in came to me about a week ago. It took awhile but was well worth the wait. Lookea from Poland sent me this card of Centennial Hall in Warsaw, which is a UNESCO site. The symmetry of this view is stunning. Of all the postmarks too, I think this one was the most crisp. She wrote telling me about her hectic day and her exams. Hope everything went well.
