I’ve always been fascinated by the pocket gramophones of the 20s and 30s. I discovered there’s a bunch of them on YouTube. The top one here is a Mikiphone, from 1926. The second one is a Peter Pan gramophone, from 1930. Some models of the Peter Pan even had a clock built into the carrying case/body of the player. My all-time fave pocket gramophone is the Gipsy, which can be seen here.
