I'm looking for an owner's manual OR any related literature (magazine
ads, etc.) on Holtzer-Cabot headphones, circa 1921 through 1926.
Here's a link to give a general idea of the type headphones I'm
talking about:

If anyone has any literature they'd be interested in selling, please
let me know! An owner's manual would be ideal. But I'm not too fussy.
Thanks in advance,
Bryan Lord
