A commercial promoting the Telefunken radio receiver.
A wizard appears in the sky and uses his magic wand to summon some musicians who float in the atmosphere and perform various songs on their instruments. The wizard puts the musicians one by one into a star-shaped box and then closes the lid. The box turns into a Telefunken radio receiver whose speakers sound with music.
Filming the commercial employed the Gasparcolor system.
