Jigsaw puzzles are all made to the highest possible quality standards. They are made from professional photo enlargements which are then sealed to a Grade A cardboard backing sheet before being cut to the specified size. The finished picture puzzle is then broken up and sealed in a plastic bag and finally packaged in a full color box. The image is printed on the box as a guide to making the puzzle.
