In about 1928 the illustrious M. Schulz Piano Company introduced a limited number of tiny 'Child Size' baby grand pianos under the 'Marionette' label. Measuring only 46 inches wide and 44 inches long, these little pianos were real pianos with the tone quality of an ordinary baby grand piano, but their diminutive size made them ideal for wealthy children's play rooms, dance clubs, boudoirs, etc. Because piano technology had reached its peak in the 1920's, these tiny pianos were thoroughly modern in design and the science and craftsmanship behind them resulted in a piano that sounded like a much larger instrument.
The tiny Marionette baby grand was available in two basic models; a conventional baby grand piano and an expressive "reproducing" player piano. The player pianos were equipped with the Schulz patented "Aria Divina" expressive reproducing player mechanism which played the piano with real human dynamics.
M. Schulz had great plans to build these little pianos in large numbers. They were advertised as being offered in elaborately carved cabinets and elaborate finishes, including hand painted Oriental style finishes. When the Great Depression hit in 1929, M. Schulz was forced to drop their grandiose plans for the Marionette line and only a few were ever actually built.
