Vintage Frog Croaking Musical Instrument Hand Carved Wood

Description

This little frog is a delightful music instrument which has been in my home for more than 2 decades. It was not new when I brought it from my family's home. I think it was a souvenir from Hawaii, purchased by my parents in the 50's or 60's. It measures 7"x 5.5"x 4" Questions are welcome
