From the glittering summer of 1900, when fifty million visitors poured into Paris for the Exposition Universelle, this hand-tinted Art Nouveau card celebrates two signature views: the imposing German Pavilion reflected in the Seine, and a broad river panorama from the Pont des Invalides — all framed by a lush chromolithographed rose spray in full Belle Époque bloom. Sent on August 24, 1900, from Paris and routed through Amsterdam, the card was addressed to Michaele in St. Pölten, Austria, care of Heinrich — a family connection reaching across three countries at the height of a World's Fair that defined the coming century. A French 10-centime Sage-type stamp frank it, cancelled at Paris on that precise August afternoon, the postmark reading "PARIS 18 / 24 AOUT 00."
