Envelope with Polish money, 1917

The Mazo Family series contains papers having to do with Frances and her family. These include publications and manuscripts in Polish and Yiddish, including Frances's school gradebooks, her mother Sonia's passport, and lists she made of books she read. Other files contain Polish money, an autograph book, postcards, and Mazo family photographs from Warsaw, Charleston, and Saint Paul. There is also a scrapbook from Frances's younger years through her graduation from college, a siddur (prayerbook) in Polish and Yiddish, and a Polish/Yiddish glossary.

A highlight of the series is the single edition of sister Norma Mazo's series of 17 caricatures of Charleston life in pen, pencil and watercolor under the title 171 King Street and a comparable collection of comic art based on the bookstore in Saint Paul, also named for its address 26 E. 4th.
