On the last picture you can see a contrasting Pewex - which was chain of hard currency shops selling imported goods:
The emergence of Pewex stores made it possible to for natives to obtain the unobtainable; a familiar sight to any foreigner in Poland at the time, these special ‘tourist shops’ offered a wide range of goods, but only in return for hard currency.
