Thank you for submitting your item for appraisal. This appears to be a rather common clear glass vase manufactured in Sweden by the Kosta factory, showing a carefully cut image of a Hanse era sailing vessel. The signature at the base most likely reads Kjellander. Lars KJELLANDER (1868-1931) was one of the leading swedish glass designers . The vase in your possession was apparently made by an expert artisan in the 1930s to 1950s after a Kjellander design. The estimate is based on similar sold at auction. There is no measurement for the sentimental value you might attach to the item.
