The A.L. Monsohn Lithographic Press (Monzon Press, Monson Press, דפוס אבן א"ל מאנזאהן, דפוס מונזון) was established in Jerusalem in 1892 by Abraham-Leib (or Avrom-Leyb) Monsohn II (Jerusalem, c.1871-1930) and his brother Moshe-Mordechai (Meyshe-Mordkhe). Sponsored by members of the Hamburger family, the brothers had been sent to Frankfurt in 1890 to study lithography. Upon returning to Jerusalem in 1892 with a hand press, they established the A.L. Monsohn Lithographic Press in the Old City of Jerusalem. According to the Information Center for Israeli Art A.L. Monsohn "created complex decorations for documents and oriental calendars that combined the tradition of Jewish art with modern printing techniques such as photographic lithography, raised printing and gilding."
At first the A.L. Monsohn Press was situated in Bab al-Huta; it was later moved to the courtyard opposite what is today the Old Yishuv Court Museum (Hebrew: מוזיאון חצר היישוב הישן) at 6 Or Ha-Hayim Street in the Jewish Quarter, where Abraham-Leib Monsohn lived with his family. The press was relocated to the Mamilla section of Jerusalem, outside the Old City, and later to Yosef Ziv Street in the Tel Arza neighborhood. According to Ismar David the press eventually had facilities in Tel Aviv and Haifa as well ("About the Monson Press" ).
The Monsohn Press produced about 300 color prints per day, the only color printing done at the time in Jerusalem. In 1894 they imported a new machine which could print 1,000 copies a day—a great advance in local printing. The founders of the Monsohn press produced Jewish-themed color postcards, greeting cards, Jewish National Fund stamps, and maps documenting the evolution of the Jewish settlement in Eretz Israel in the nineteenth-twentieth centuries (e.g., Moses S. Klier's Mappat Eretz Yisrael Ve-Suriya, 1903; Mappat Eretz Ha-Qedosha Li-Gvuloteha, 1905); religious material such as decorative plaques for synagogues, portraits of Old Yishuv rabbis such as Shmuel Salant, Mizrah posters indicating the direction of prayer for synagogues, memorial posters, and posters for Sukkot booths; color frontispieces for books such as Pentateuch volumes and the early song collections of Abraham Zvi Idelsohn (e.g., Shire Zion, Jerusalem 1908); artistic wedding invitations; and labels, packaging and advertisements for the pioneering entrepreneurs of Eretz Israel. The texts appearing in the Monsohn products were in several languages: Hebrew, Arabic, Yiddish, English, German (e.g., a c1920 trilingual Hebrew-English-Arabic "Malaria Danger" broadside warning the public of mosquitoes spreading malaria). Many of the brilliantly colored postcards and maps can be seen online, as can the artistic invitations to his children's weddings which Monsohn published in the Jerusalem Hebrew press (e.g., that for his son Menachem Mendel Monsohn and his wife Zipporah on the front page of the 24 June 1914 issue of Moria).
The Monsohn Press received special permission from the city's rabbis to print for Christians and Moslems, so long as the material could not be used to proselytize. While Eretz Israel was under Ottoman control, Abraham-Leib Monsohn also printed the maps for the Ottoman military leader Djemal Pasha, in his headquarters in Mount Scopus.
