It is important to point out that the parts have the usual shape and interlocking (with many frames Ravensburger puzzles with 30-50 parts is not so !!!). The real motive rises above the puzzle pieces away even 1-2 millimeters in the frame. This facilitates the start, because you can then invest edge portions unerringly to the frame.
On the frame background the subject is not shown (the subject is actually displayed anywhere, except in the finished puzzle set), but the shapes of the parts are traced. Through this preparatory drawing can be the puzzle also different from the usual approach: one (our little one can do that already) immediately deposit the part precisely to the correct prescribed space.
My daughter and I can only recommend this puzzle and if this puzzle is no longer a challenge, then the difficulty can be increased with "horses in the pasture" (25 parts)
