An incredibly rare and highly collectible piece of early 20th-century novelty history. This is the classic "Fenster-Radau" (variously translated on the packaging as "Window Breaker" and "Carreau Cassé"), a vintage acoustic prank or "crash-bang" joke. Popularized in the first half of the 20th century and featured in historic magic and joke catalogs like Davenport's, this gag consists of a series of thin metal plates. When dropped together onto a hard floor, the acoustic resonance of the overlapping metal plates creates a startlingly realistic sound mimicking a window shattering or glass crockery breaking.

The lot includes the original paper envelope container featuring graphic mid-century style illustrations of a baseball or rock shattering a multi-paned window pane, complete with instructions and titles printed in German, English, and French.

• Contents: Original printed paper envelope sleeve, 6 original metal plates.

• Era: Circa 1930s – 1950s.

• Dimensions: Envelope approximately 75mm x 125mm.

• Condition Report: Pocket sleeve shows age-appropriate wear, minor tearing at the top opening tab, and slight discoloration consistent with age. The interior metal plates have developed a rich, heavy natural oxidation and surface patina over the decades, preserving their authentic vintage look.

Estimated Price: R 350 – R 600
