This delicate porcelain bowl or vase was produced by Belleek in Ireland c 1965-1980. I have not been able to accurately identify the pattern name, although I have seen it called Nickel Flower. It has raised slanted areas around the body of the bowl that resemble some kind of fern fronds to me and scalloped tabs at the rim.
The interior is done in yellow luster. The bowl is in excellent condition. It has the third green mark on the underside that dates it to 1965-1980. It measures about 4.5" in diameter across the fullest part of the body, and stands about 3.75" tall.
