The Presto Clock Vanish (also known as "My How Time Flies") is a classic comedy magic trick. A metal-look clock is placed behind an ornate screen or board, but when the board is turned around, the clock has vanished and the phrase "How Time Flies” is printed on the board. This classic UF Grant/MAK Magic effect comes complete with the board, a chrome metal clock, and complete instructions. The effect is easy to do and requires no sleight-of-hand. Note that this is a vintage piece that is in very good condition. We only have one and shipping in the USA is included in the price. 001CBMPRESTOCLOCKVAN
