This creates the puzzle! He likes the locomotive, the picture is beautiful (which is the butterfly, let us now piece together the hare, etc) The puzzle is indeed in a frame. Super is that when the pieces are there, even the outlines of the parts are easily stamped. This the little parts find it easier then to arrange properly. Afterwards I simply inserted a sheet of paper. Since he was first surprised but then cheerfully going puzzling.
So super (alone) to provide for a 2 years 4 months old child already real.
