Very nice puzzle, good quality. Carton rather thick and solid. Cardboard "support" gives the forms, but does not have the model of the drawing (so no model for this puzzle ca can hinder younger at first) Unlike another reviewer, I did not find dull picture, on the contrary it is rather pretty. Please note, not only parts are not square, but in fact they do not fit together. They touch only. The AC also can interfere smaller. Despite this good product.
