Form of the 'fat and happy Buddha', found in Thailand -. He is meant to be carried for "good luck". Very few very small authentic amulets like this exist. (perfect to wear!) At least 200 to 300 years old- possibly a few hundred years older. I'm digging into the recesses of my collection and putting up the last things I can find that have been with me for decades as I finally downsize as I move into retirement. Looks to be 18th or likely much earlier.
