Sold Retro yellow music duck for above the cradle

Sold A retro music duck for above the cradle from 1974! Such a dot, the color is warm yellow and he or she looks so happy! The funny thing is that the wings move very slightly along with the music. Unfortunately, we do not recognize the song. The retro music duck works well, can be hung, is marked Sankyo, made in Malaysia, 1974 and is in good condition. See also the additional photos.
