My mother collected these on Hayama Beach when we lived in Japan 1959-1962 and displayed them in an antique Japanese Hibachi covered with a piece of glass.
We moved back to the US. I took my children on a vacation to St. Thomas in 2004 and upon returning I added the green "sea biscuit" (upper left) I had found on the island there. My mother had a little hissy-fit over me adding to what was intended to be "Japanese only" so I removed it after I took this photo.
