Hi all,
I have a trick I came up with years ago but unsure if it is published anywhere. I have a quarter signed and vanished. Throughout my act I introduce a miniature liquor bottle; unopened with the alcohol still inside. At the end of my routine the quarter is inside the bottle, signed, with the liquid still in it. I hand the bottle away as a souvenir for the spectator to keep. I once showed this to Eugene Burger years ago and he referenced seeing something similar but I can't recall what he referenced. Any clues? I want to ensure I am not copying anyone before I consider production of this trick.

Thank you,
