This exhibition tells the story of Warsaw's domestic servants, who made up nearly 20% of the city's workforce at the end of the 19th century. Largely invisible to both their contemporaries and, later, historians, these women were nevertheless a key social group and an indespensible part of many middle- and upper-class households of yesteryear. The Museum of Warsaw is now seeking to tell their story though a collection of 400 objects from the 19th and early 20th century, in addition to materials from communist times, when having a servant became a huge no-no, and more contemporary works of art.
