Street posters, tracts, prospectuses, and newspapers, printed mostly during the 1848-9 Revolution in Berlin (capital of Prussia), later collected and numbered by Andrew D. White during his stay in Berlin as the fourth U.S. Ambassador to unified Germany (1879-81). Broadsides collected by A.D. White on the national movement and revolutions in the German states, documenting the movement toward national unity and democracy there during the 1848 revolution, aka "the Spring of Nations." Most flyers, newspapers and pamphlets were produced in Berlin and are about the national-democratic movement in Prussia; the rest are related to the first German National Assembly, which opened its session in St. Paul's Church in Frankfurt in May 1848; finally, a few items concern the case of "Greater Poland" or the Polish uprising against Prussian forces. Some documents are illustrated with caricatures.

The collection includes, e.g., a lithograph by Boehmer showing a barricade and a street fight on 18-9 March 1848 (box 2, #232); the two proclamations issued by King Karl Wilhelm IV of Prussia in 1848, calling for the removal of the barricades and promising the departure of the troops from the city and far-reaching political reform: "An meine lieben Berliner!" (18-19 March 1848) and "An mein Volk und an die Deutsche Nation" (21 March 1848) (oversize leaf 1); an anonymous poster protesting the return from exile of the counter-revolutionary "Kartätschenprinz" Wilhelm of Prussia, and claiming that "Only the popular will can recall this prince!" (June 1848) (oversize leaf 2); two proclamations by the founder of the Verein für Radikalreform Friedrich Wilhelm Held, 1) making public his decision to run for Commander of the Civic Guard or Bürgerwehr (1. August 1848), and 2) detailing his views on the future German Constitution (September 1848) (oversize leaf 3); the first "special new year's issue" of Kladderadatsch, a famous satirical magazine first published in Berlin on May 7, 1848 (oversize leaf 3); street posters informing the Berliners of the appointment of a new cabinet led by ultra-conservative Count von Brandenburg; as well as of General von Wrangel as "Oberbefehl über die Truppen in den Marcken," both with the unofficial mission of crushing the "rebellion" and recapturing Berlin (November 1849) (oversize leaf 5).

The collection also contains several advertising prospectuses for the panoramas and dioramas created and exhibited by Karl Wilhelm Gropius between 1836 and 1848, showing the potential for a mass medium based upon reproduced moving images (box 1, #16, 23, 40, and box 2, # 101, 153, 217, and 241).
