This puzzle have been missing one piece in it for years and years. I was really bummed out about it too, cuz it sat kinda in the middle, where your eyes went. So it's been a bit since I last had this out.
Then last summary I moved house. And lo and behold, miracles of miracles. I found the missing piece! Going through old stuff in a box. And there it was. All innocent like. I couldn't believe it!
So yeah, definitely time for this thing to return to it's rightful place!
