Up for grab is a very unusual gadget for rotary style telephone. 

It plays music while you please a call on hold, this is a very cool and can still be used for any modern mobile as well. just place you phone on top and it will play music as a standby theme song.

still in original box, never used. In mint cosmetic condition. I have never come a cross another one like this.

This is part of my private collection over many years, and will surely be a proud addition to your stable.

I have many awesome vintage items with interesting timeless designs, and conversation pieces. follow me for more interesting listings that you will like.
