The Talking Machine Forum — For All Antique Phonographs & Recordings

Hey there friends, I am looking for an "Edison Listening device". I attached a pic for your reference.
Your valued reply is much appreciated in advance. Warm regards Deb

The graphics on the package place this in the late 1930's or 1940's. Therefore it would be an accessory for a dictation machine.

there is one on ebay right now
