Fams, a promotional item for the 2006/7 title Yoshi's Island on the Nintendo DS !.
This was a commercially available item , i believe a few different styles exist for this title (there def were ones for other Nintendo titles).
Bottom of puzzle board has the 2006/7 year stamp and NINTENDO denotation. - puzzle is nestled inside a "border frame" piece. You can see it in the photos - puzzle pieces do not go from edge to edge, there is a border like a picture frame, and the puzzle pieces assemble inside of it!
Beautiful colors and art all around!
