Tenth Zionist Congress in Basel – Real-Photo Postcards

Two real-photo postcards, taken during the 10th Zionist Congress in Basel [August 1911].
Clear and sharp photographs. A large painting of Theodor Herzl is seen in the background, surrounded by a striped flag, a Magen David and the word "Zion". David Wolfsohn delivering a speech is seen in the center of the stage, surrounded by members of the Zionist Organization, with a second flag at the front of the stage, in its center the words "Gur Aryeh Yehuda" encircled by twelve stars. The back of the cards carry the ink-stamps of the photographer and artist Robert Spreng (1890-1969), a pioneer of modern photography and the "New Objectivity" movement, who owned a photography studio in Basel. Very good condition. A few stains on the verso.
