The rugs are an old norwegian and swedish traditional way of making rugs and has been so for a long time. It has become quite popular again especially in old houses.
I showed the picture to my uncle to see if he could recognize anyone. He knew a man called Reidar Waleur, he would bee somewhere between 90-95 years old. He is now dead. He worked has a driving licence teacher here in Halden. He has a daughter, Anita, born in 1940 in Strømstad, Sweden. Maybe that`s why it is so hard to track the family down. Strømstad is only 30-40 km from Halden. I`m going to check out some info. tomorrow ( it`s over midnight and I should go to bed even if I have holiday).
