Elpiano

The entry for the Elpiano in a Hohner catalogue from April 1973:

The yellow line indicates that everything below the instrument itself is "available as an accessory."

Here's my translation of the text:

HOHNER - Elpiano

A super light, portable model for pros and amateur musicians who are often on the road.  In the sound of the time, space-saving, easy to transport, very mobile.  Especially to be used as a 3rd manual.  For protection in transit, a good-quality plastic bag is available.  A collapsible stand allows the HOHNER Elpiano to be set up as an independent instrument.  Suitable headphones can be directly connected to the instrument.  For use in the home, a 25-Watt amplifier, specifically developed for the Hohner Elpiano and hung on the stand, is available.
