My kid sister had an earlier version of this telephone as a baby, 50+ years ago. She dragged it all around the house, "talking" on it (especially whenever my mum was on the real 'phone), and I just sent it to my newborn first cousin twice removed -- my cousin's daughter's daughter -- in Australia. She's too little to play with it just yet, but bright and inquisitive--so I know it won't be long before it becomes her best toy friend, too.
This toy has been around for years my own children had it now I am buying it again for my grand children Its a very good way of getting them use to talking on the phone. Plus they can pull it along on the string attached.
