Shuffled Symphonies were short, illustrated fantasy stories in the British Mickey Mouse Weekly. Some of the episodes included time travel via Doctor Einmug’s time machine. The four that I know about include a trip to Stonehenge (1 Jan 1938), to visit Sir Walter Raleigh and Elizabeth I (12 Mar 1938), a visit to Shakespeare (6 Aug 1938), and a trip to a robotic future (26 Nov, 1938).
