Great news! I finally managed to find the last of the Kaj Stenvall duck puzzles. I first decided to try and collect the entire series in early 2019, and by July 2019 I already had 29 of the 30 puzzles that I’m aware of, and I’ve been looking for the last one ever since. When someone had a glued and framed copy for sale, I even considered getting that and taking it apart, but I’m really too lazy for something like that. The most frustrating moment came in October last year, when there was one for sale on a Finnish site (tori.fi), but I was in Dortmund, the seller offered pickup only (no shipping), and it was located 200 km from Helsinki in a place where I didn’t know anyone. Since I couldn’t possibly ask someone to drive 400 km in the middle of a pandemic for a puzzle, I just cursed silently to myself and wondered if I would ever find that last puzzle.
And then, on Monday, there was again a copy available, and it wasn’t even for sale, but given away. I was lucky I saw the posting almost immediately, and managed to get in first. It was, again, 200 km away, and I would have happily driven, but the previous owner very generously offered to send it if I paid for the postage. Which I was very happy to do, of course, in fact I was so happy that I paid a bit extra. Today I finally got my hands on this:

You can see all of the puzzles in the series on my dedicated page. Now I just have to do them all 🙂
