Antiques are a popular commodity in Poland and you'll find no shortage of antiquated oddities in Wrocław. As you walk about town keep your eyes peeled for signage with the inscriptions 'Antyki,' 'Antykwariat' and 'Starocie' (junk); ul. Kiełbaśnicza (A-3) is a good place to start. Knowledgeable dealers offer prices comparable with the rest of Europe, but there are still plenty of bargains and undervalued treasures to be found. Bear in mind that if you intend to take art that is more than 50 years old and of a potentially high value out of the country, you'll have to get some papers in order first. These can typically be provided up front by proper dealers, but make sure you check. Happy hunting.
