The wonders of nature are endless, like being able to assemble a 500 piece puzzle in one of the most challenging motifs - the ever changing beauty of the sky. A jigsaw puzzle is a tiling puzzle that requires the assembly of often oddly shaped interlocking and tessellating pieces. Each piece usually has a small part of a picture on it; when complete, a jigsaw puzzle produces a complete picture. The PRINTWORKS "Sky Series" takes an image of the sky at a particular time of day and allows you to re-create it. People often do puzzles to relax and unwind ... what better way then while watching the sun set and rise!. Collect all 3 - Dawn, Dusk & Night.
