Vintage plastic miniature grand piano music box, plays 6 tunes.
The three legs fold in to the base and the keys move when pressed. You can set it to automatically play music, or set it to play the tune when the keys are pressed. This doesn’t have functional music keys, it can only play the pre-programmed tunes.
The lid holds up with out support, but there is an arm for extra realism. The key cover folds up and down, as does the music sheet support. 
Works off two AA batteries (not included). The battery cover is present, but I left it off to take the photos. It secures in place with one small screw.  
In good vintage condition. Tested and working. There are a few marks to the lid, and the box is worn. Please see photos for more details. 
Etsy videos don’t play sound, but a video is available upon request.
