Pashkevilin (Broadsides)
There is now a book devoted to these. The book, Pashkevilin: Modo’t Kir u’kruzot Pulmus b’rehovot haharedi (“Broadsides: Wall Announcements and Polemical Proclomations in the Ha’redi Street”) contains three articles and 150+ pages with pictures of these broadsides.
The first article is by Menachem Friedman (a recent topic on AJHistory) on the history of these broadsides. (This article is available online here.) The second article focuses on death notices and the third article focuses on the language of the broadsides. The rest of the book is devoted to pictures of these broadsides. This section is divided into seven sections by topic: the controversy about the Yishuv haYashan; HaHinuk haTohar (Jewish education); Zionism; Hillul Shabbat; divisions between various camps of Orthodoxy; Tzniut; and various fights.
