Rosendahl Kay Bojesen Seagull Mobile. As a keen birdwatcher, Kay Bojesen created his own interpretations of several bird species. Now the time has come to introduce another feathered favourite to the flock, as Kay Bojesen Denmark sends the Seagull soaring. Kay Bojesen designed the Seagull in 1954 for the Carpenters’ Guild’s jubilee exhibition. Just 23 of these seagulls were originally made.
