Wonder Silk Box (Silk Wonder Box) by Viking Mfg.

This was invented by János Bartl from Hamburg in Germany c. 1934, and licensed to Davenport’s in April 1934 to sell under the name Demon Wonder Box. It was marketed in the 8th issue of the Demon Telegraph, a house-magazine from Davenport. In this early version only two sides could be opened. c. 1952 an advanced version came to the market with the name “Silk Wonder Perfect” and you could open all four sides as can be see here. Brema & Co. began making this version c. 1946 and Viking purchased the rights to Brema c. 1978.

Effect: Performer shows a handsome plated box with thin sides. Holding it in one hand the front and back drop down and the top opens. There is no room to conceal a pin. Box is closed and immediately a number of silks are produced. One silk is replaced in the box and vanishes and is found elsewhere. Box may be shown empty after each production or vanish. Box may be thoroughly and minutely examined without the remotest possibility of anyone discovering the secret.

NO MIRRORS, False Bottoms, hollow sides, clips, threads, back palming, fakes, body loads or anything of the kind. Box can be taken straight off the hand and handed for inspection. The Wonder Silk Box is a handsome, beautifully finished article. No sleight-of-hand required and the effect can be performed to perfection after a few minutes trial.
