This teapot, belongs to the 'Sonja Collection' launched in the 1960's by the legendary ceramic company Søholm on the Danish island of Bornholm. 
It was named after a little charming girl from a very popular children’s TV program at the time called: Sonja from Saxostreet. (Sonja fra Saxogade). It comes with matching sugar and milk pots.
 
The clay on Bornholm is of a very high quality and therefore Bornholm has always attracted a lot of ceramists. Søholm Pottery was founded in 1835 by Edvard Christian Sonne and Herman Sonne Wolffsen.

Søholm has established itself as one of the top makers of Scandinavia midcentury icons of stoneware.
