Vintage Early Made in Japan Salt & Pepper Shakers Girl Singing and Boy playing

We have a cute set of salt and pepper shakers. They are vintage with their original cork stoppers. They are marked "Made in Japan". The girl is singing while the little boy plays a guitar. There are no chips, cracks or crazing. The paint is intact. They are approximately 3.5 inches tall. If you have any questions please message me. Thank you for looking and have a great day!
