The Joseph Knapinski house is an example of a "Polish flat", a cottage with a raised basement and a separate entrance. The basement provided an additional living unit either for extended family or for rent.
The University of Wisconsin-Milwaukee acquired the collection through the Assistance of Polanki, the Polish Women's Club of Milwaukee; and Roman Kwasniewski's daughter, Adele, and her husband, John Kaczmarowski. Representative Walter Kunicki and Senator John Plewa secured state funding for the processing of the collection.
