I found this curiosity amongst a box of very old records. It's a drinks coaster advertising Idris Lemon Squash that doubles as a vinyl record. Unfortunately I don't have a gramophone so have no way of listening to it. It name-checks 'His Majesty' so pre-dates Queen Elizabeth (1953). If anyone knows more about this please let me know!
