Nice comparition! If You allow me to add a detail, I'd like to specify that in the period of the most ancient postcard Poland was a part of the Russian Empire (1815-1917) and the official name of this town was Жешув. The pronunciation was the same of nowadays: approx. "Zhezhoof", if it would be written in English.I visited that part of Poland by train and stayed there 20 days in the summer of 1988. Probably many things, from that period up to now, changed a lot. But I still dream about the strawberries of that area of Poland. They were (and are) the most tasteful ones I did ever eat!
