Ad-Infinitum or Imagino | Robert Harbin, ca. ?

Magician shows two square tubes, obviously and actually empty, and places them on a tray. The magician then proceeds  to produce an unlimited number of handkerchiefs from the one tube and puts them into the other (one by one). This is repeated ad-infinitum. At the end both tubes are shown to be empty

Entirely self-contained - no skill or sleight of hand needed. Complete with mahogany tray, hinged tubes, and silks. Maker unknown. Original instructions included.
