This is a vintage Gerold Porzellan planter made in Bavaria.
The planter is a white swan. On the bottom is a blue and gold label reading "75 Jahre (75 years) Geroldporzellan Bavaria."
Gerold Porzellan was in business from 1904-1997 so this piece may be dated around 1979 since it is a 75th-anniversary piece.
It measures about 3.5" tall, 5.25" long, and 2.5" wide.
The planter is in good preowned condition with some stains inside
