Is this a Arne Hovmand Olsen two seat sofa?  

At first view it appears to be a Hovmand-Olsen, but more details are needed to make a real valuation.
Side view - back view - photo without cushions - close-up of wooden joints - and down on your knees when taking pictures, not taking pictures from above ...

Here are a few more pictures that are available right now from the seller

and one more

last one - thanks

No doubt, it's real.

Thanks so much for responding - we have been looking for a love seat / two seater and my wife and I love the lines of this one.  Took me a while to find the model 225 by AH and have had no luck finding any piece other than the single chair.  Now just have to get it..

Again, thanks

Try finding a stamp, like this one, Mogens Kold

I will try and let you know - your help is much appreciated.
