plastic design

My mother's training in graphics and packaging meant that items of design would appear in our home from time to time. This plastic lampshade arrived with us in the 1970s - flat packed and in bits. It was trickier to construct than any Ikea equivalent.  We were encouraged to help out in its manufacture, seeing it as a game. Consequently I never really registered this item as a valid design object until recently.

On a visit to the Nordic Craft and Design exhibition at Manchester Art Gallery I spotted our lampshade on show.

It's immensely pleasing to know that this old plastic object is a piece of late 1960s Danish design by Lars Schiøler

The Butterfly pendant is hanging in my office studio. Pride of place.

Does anyone have any design information on this other shade?
