A BEECH, METAL AND BONE TABLE LAMP, CIRCA 1929

cf. Prouvé (ed.), L'art international d'aujourd'hui, 'Le Métal', Paris, 1929, pl. 9 for a highly comparable table lamp, edited by D.I.M.

Unlike the version edited by D.I.M., the present lamp has a bone light switch rather than a wood one, suggesting it might be a prototype.
