Very Rare Vintage Cloisonne Panda World Pin Badge Chinese Japanese Mama with Cub

Very Rare Vintage Cloisonne Panda World Pin Badge Chinese Japanese Mama with Cub I have tried to find information about this pin and have not been able to. If anyone knows, please let me know. There is writing on the back (see picture). I do not know what language this is and was unable to get it translated. I could not find any information on this pin. So, if anyone know, please let me know. Please see pictures for details and judge for yourself on the condition. I am hoping that I have taken enough pictures. I show how the enamel went over the edge a bit and that there is some wear, but overall, in good condition. Thank you for looking.
