Hi,
See also the frontispiece to the book and exhibition catalogue
"Austerity to Affluence, British Art and Design 1945-1962" which shows a four drop version of the light fitting with an example of each style of the light shade - long, plain cylinder included with three, different, bubbled shades. Also shown on page 103 as item ref PD46 with a reference for
Design magazine no.132 December 1959.
The price it sold for, complete with ceiling fitting and drops, in the exhibition, held in 1997, would make your hair stand on end - however long it is

But this was a groundbreaking exhibition held by Target Gallery (Geoff Rayner and Richard Chamberlian) in conjunction with The Fine Arts Socitey.
