Paper Shtetl, “a Complete Model of an East European Jewish Town,” in the Kemnitzer Paper Model Collection (courtesy of David A. Leavitt’s favorite is a black-and-white “Paper Shtetl” advertised as: “A complete model of an East European Jewish town.” It features two-dimensional villagers, trees, chickens, and cows to position among thatched-roof homes. A 1984 article in the New York Times described its design by publisher Schocken: Others celebrate local or distant marvels, as souvenirs or educational toys, or recall a lost past. So before a display of the miniature architecture could be installed, museum staff, architecture students, and volunteers all pitched in to carefully construct color copies of selected models, with the more elaborate examples taking weeks to erect with scissors, glue, and razor blades.Īs curator Sarah Leavitt, who organized Around the World in 80 Paper Models, explained to Hyperallergic, the time making the models “does give you this connection to the structure you’re building.” And for some of them, like a paper power plant produced in Scotland, encouraging a familiarity with a new building was the goal of the model. But he never assembled the 4,500 pieces he donated to the National Building Museum between 20. WASHINGTON, DC - Architect David Kemnitzer spent decades collecting paper models of castles, nuclear power plants, modernist houses, farms, and skyscrapers, starting from his childhood in the 1940s.

The reason people still use blueprints is because it is an inexpensive process. ![]() This diazotype method produces dark lines on a white background, and is the popular method used today for reproduction of large-format drawings. The chemicals on the paper acquire color only in the areas not exposed to light. Ammonia gas or solution is used as a developer after exposure - it neutralizes the acid and allows the remaining diazonium salt to combine with the reactant to create a blue dye. The semi-transparent original is placed on top of the sensitized paper, and a copy of the same size as the original is made by direct contact. In the diazotype method, the paper is light-sensitized with a mixture of a diazonium salt (used in the manufacture of dyes), a reactant, and an acid that keeps the diazonium salt and the reactant from reacting with each other. This produces a negative image, with the drawing appearing in white against a dark blue background. The exposed paper is then washed in water. Where the areas of the sensitized paper are not obscured by the drawing, the light makes the two chemicals react to form blue. The sensitized paper is then exposed to light. The drawing to be copied, drawn on translucent paper, is placed against paper sensitized with a mixture of ferric ammonium citrate and potassium ferricyanide. ![]() ![]() Blueprinting is the older method, invented in 1842. ![]()
