World’s Smallest Playable Record
The record holder for the world’s smallest playable record is a tiny shellac pressed by HMV in 1924, a functional miniature gramophone record containing a recording of Peter Dawson singing ‘God Save the King.’
It was originally created as part of a doll’s house for England’s Queen Mary that began construction in 1920.
The doll house contained functional items 1/12th the size of their real-life counterparts, including a functional miniature gramophone seen below.
The record is 33.3mm / 1 5/16th inches in diameter and plays back at 78rpm. 35,000 copies were pressed.
