Fly-To Bird Cage. Vienna: S. Klingl, ca. 1920. Magnificent mechanical device allows a bird cage, removed from a handsome stand, to vanish, then visibly reappear in a matching empty stand some distance away. Height 17 ??. Hallmarked. Very good working condition. Rare. A prop manufactured by several prominent European magic builders at the turn of the twentieth century, and uncommon in any form. This is the first Klingl-made model we have encountered. While taller than the Willmann model, the cage that reappears is permanently affixed to the stand that holds it.
