78 rpm record for the miniature gramophone in Queen Mary's Dollhouse (Queen Mary was the consort to King George V). Reputedly the smallest working gramophone record ever made, it was one of six recorded under the HMV (His Master's Voice) label. It contained 10 seconds of audio. The dollhouse was shown at the British Empire Exhibition in 1924 and was extremely popular. Replicas of the record were sold to the public at HMV retail stores (Handy 2021, 5).
