Welcome ultra rare friend! Saw this test carpet from 1960 many years ago but it was then sold. Always wanted to have it and now, 18 years later, it popped up for sale again!
The design ”Geometri VII” is one of Verner Panton’s earliest and I would be surpriced if many more flat weave carpets with this pattern has survived. Here are some quick pictures, also one of the still remaining(!) original tag wich also tells it was made in England for Unika Vaev.
