The first Stenvall puzzle with portrait orientation – I only realized, when I started on it. There is one more puzzle with this orientation in the series, and I think they might have been the last to be produced, because the pieces are thinner and the fit is not as good as with the other puzzles in the series. The less than stellar quality made it less enjoyable than usual, but still ok.

The title is an exact translation of the Finnish title, although the word open is also used figuratively in the meaning “undecided”, and without context that would be my first interpretation of the Finnish sentence, but here, of course, we can see a literally open window in the image.
