I got the puzzle last Christmas because I'm really into maritime motifs. ;-) I'm also super happy on the North Sea, but unfortunately all too rare. Since the puzzle was a nice alternative. Unfortunately I personally have very little patience and can not concentrate myself well so long the puzzle, especially all the blue parts, has demanded a lot of me. Ultimately I did but it was done & then all the more proud. ;-) All parts fit into one another super. Unfortunately, it is slightly larger than 50 x 70! Although at each side only 1 mm but it is enough as the you can tell if you want to frame it. Fortunately, I decided for a picture frame or frame so I could hang it anyway but I had the parts at the points where the bracket clips are sprains.
