This is a postcard from a city Łódź, in Poland. I got it through a trade with Kuba who lives there, also through Postcrossing.
Łódź is the third-largest city in Poland, located in the central part of the country. It is the capital of Łódź Voivodeship, and is approximately 135 kilometres (84 mi) south-west of Warsaw. The city’s coat of arms is an example of canting: depicting a boat, it alludes to the city’s name which translates literally as “boat”.
