This circus calliope pull toy has a lot of things going on. When it is pulled along the umbrella and the lion turn, music plays and the horse articulates up and down due to its wheel axle being placed off center. These pull toys music boxes never seem to work so I do not know what the song is. The base and whells are solid wood and the remainder is Tekwood. It measures 19″ x 5.25″ and 11″ to the top of the umbrella. This appears in a 1950 catalog.
From my private collection.
