Tyra Lundgren. In 1935, living in Paris, she started freelancing with Kosta. She designed her work at her Paris studio and sent the drawings to Sweden. Kosta executed her work based on the drawings. She kept to a ‘nature’ theme, decorating the vases with sandblasted fish or doves. In most cases, she used a monochromatic palette of blue, brown or green glass. She worked for Kosta in 1935 and 1936.
