This fun little swan is actually a creamer. It is well marked on the bottom with the 6th green mark "R in circle - castle - Belleek - Ireland - Scanta in Eirinn - Reg. No. 0857". It was made by Belleek. This mark was used from 1965-1980. It is very fine, thin porcelain. This swan's head and wings are yellow lustre. The rest is off white. The yellow is not as bright as in my pictures. This creamer is 3-3/8" tall x 2-1/2" wide x 4-1/4" deep.
This creamer was used. But it does not have any chips or cracks.
