A portrait miniature is a miniature portrait painting, usually executed in gouache, watercolor, or enamel. Portrait miniatures developed out of the techniques of the miniatures in illuminated manuscripts, and were popular among 16th-century elites, mainly in England and France, and spread across the rest of Europe from the middle of the 18th century, remaining highly popular until the development of daguerreotypes and photography in the mid-19th century. They were usually intimate gifts given within the family, or by hopeful males in courtship, but some rulers, such as James I of England, gave large numbers as diplomatic or political gifts. They were especially likely to be painted when a family member was going to be absent for significant periods, whether a husband or son going to war or emigrating, or a daughter getting married.

A decorative box is a form of packaging that is generally more than just functional, but also intended to be decorative and artistic. Many such boxes are used for promotional packaging, both commercially and privately. Historical objects are usually called caskets if larger than a few inches in more than one dimension, with only smaller ones called boxes.
