These delightful porcelain Porsgrund pieces by Grete Renning perfectly capture the return of birds in spring. Soft shades of light and dark blue blend together in a simple yet striking style, depicting a flock in V formation gliding over what looks like a freshly planted farm field. The design starts and ends with the trailing birds, leaving part of the rim clean and white. At just 3 inches in diameter, they make a charming addition to any butter pat collection.
