Of irises on a variegated green ground, the frame of stained beech with bentwood rim and beech plywood stretcher. 

This technique of beadwork under glass is known as 'Cloisonné Glass' and was patented in London in 1897 by Theophil Pfister and Emil Barthels.(1) The Cloisonné Glass Company (presumably owned by Pfister and Barthels) of 40 Berners Street /Oxford Street, manufactured screens, windows, furniture and smaller items at the turn of century and was still in production in 1905, when they published a trade catalogue which describes the technique in great detail.(2) See also Dr. Sebastian Strobl's paper entitled, 'Painting with Beads - The work of the London Cloisonné Glass Company', for a description of the technique.(3)
