1940s Guitar Playing Frog Faux Marcasite Brooch - 2.3cm Tall

Hopping to the beat this little guitar playing brooch is full of the joy of the very best music.
Made of a silver tone light metal and decorated with faux marcasite, he is
2.3cm tall 
In excellent unused condition.
The last photo shows the original display stand that this animal orchestra was pinned to when I found it.
