Thomas Kellein, Alvar & Aino Aalto Design, Collection Bischofberger, Ostfildern-Ruit, 2005, p. 180 

Overall very good condition. The original white lacquer in good condition with light and scatter scuffs and scratches as is consistent with gentle use. The third tier with a thin, vertical mark. Also this ring with very slight bulging at the areas of the internal screws and subsequent crazing. This is very minor and not visually obtrusive. There are a few minor areas of scattered surface dirt. A popular Aalto model, this light presents well overall. Sotheby's does not guarantee electrical components and suggests having all wiring inspected by a licensed electrician.
