- 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. In some cases more advanced types have appeared on the market, such as spherical jigsaws and puzzles showing optical illusions.

- Jigsaw puzzles were originally created by painting a picture on a flat, rectangular piece of wood, and then cutting that picture into small pieces with a jigsaw, hence the name. John Spilsbury, a London cartographer and engraver, is credited with commercializing jigsaw puzzles around 1760. Jigsaw puzzles have since come to be made primarily of cardboard.

- A national flag is a flag that symbolizes a country. The flag is flown by the government, but usually can also be flown by citizens of the country.
Historically, flags originate as military standards, used as field signs. The practice of flying flags indicating the country of origin outside of the context of warfare became common with the maritime flag, introduced during the age of sail, in the early 17th century.
