PEEPSHOW. PANORAMA DER BERLINER GEWERBE AUSSTELLUNG [PANORAMA OF THE BERLIN TRADE EXHIBITION]. Berlin: Oscar Michaelis 1896. 4 7/8" wide x 6 1/8" opening to 16". Fine condition in pictorial slip case (one flap neatly and unobtrusively strengthened). When extended, the 6 color lighographed scenes offer a detailed three dimensional view of the main hall of the Exhibition. The final scene has a carved medallion that is visible even when the peepshow is closed. The slip case has a beautiful color lithograph on one side and a colored plan of the Expo on the other. Although not called a "World's Fair", this was a technicality. When completed it was larger than any previous fair had been (more than 1 million square yards), featuring nearly 4000 participants and attracting 7 million visitors.
