The hill-and-dale grooves were cut into a thin coating of plaster-like material on the surface of the postcard. One of the stated advantages of Phonocartes was that they ensured privacy—they were only "readable" if you had the special Phonopostal gramophone. Of course, that only worked if the intended recipient had the special gramophone.
