A bill is borrowed, and the owner asked to sign it, or note the number. The bill is folded, wrapped in a hanky, and given to the owner to hold. The performer produces from his pocket a solid "gold" tube, which is locked. The bill vanishes from the handkerchief, and reappears inside the locked tube. An ornamental model of the classic Bill Tube, precision machined from brass, engraved and plated in gold.
